Is immediate reapplication fruitful for UK business visit with more documents as evidence?

Our university delegation comprising of 15 female faculty members of English have been invited to attend a 7 day training session of English Language Teaching Methodology in redacted University UK. Every year a delegate visits this university to get the training. However, this year the visas of all of us have been refused. My visa has been refused due to following reasons:

1- In order to assess your intentions i must consider your circumstances in Pakistan based on the information you have provided with application. All applicants are advised to substantiate their circumstances. We expect applicants to provide this information as it assists us in making an informed assessment as to whether they intend to comply with the terms of visitor entry clearance.

2- You state you intend to visit UK to attend Language Teaching Methodology and British Culture and Society training and have submitted a letter from redacted university UK confirming that you have been invited to attend the training. The documents that you have submitted do not show any professional requirement for you to attend this course however and it is not clear why you wish to take part in this course. 3- You state that you intend to visit UK for 7 days and the contact time for the course in redacted university UK is 20 hours. The documents that you have provided do not demonstrate what else you intend to do with your stay in the UK. I am not satisfied with your intentions as stated.

4- You state that your employer redacted University Pakistan will pay all costs for your proposed trip and you have submitted a letter from them confirming that they will pay for your expenses including your flight, boarding and lodging. The documents that you have provided do not demonstrate that your employer has the required funds therefore i am not satisfied that they can provide support to you for your intended visit. Your application is refused under paragraph V 4.3 of immigration rules.

5-I am not satisfied that you are genuinely seeking entry as a visitor and you intend to leave UK at the end of your visit. Your application is refused under paragraph V 4.2 a and c of the immigration rules.

What kind documents do i provide to state I will be back to Pakistan the very next day the training is over? I did provide flight details and do not have any property here in Pakistan and am unmarried.

I do not wish to take part in any other activity other than the said training. How do i prove that?

How do i prove that my university has sufficient funds. It is so obvious that the university has funds as it is one of the leading universities of Pakistan. Moreover, they provided a letter stating they are providing and supporting me financially. What else is required on part of the university?

I am English Lecturer (teaching language to undergraduates)- mentioned on letter issued by university where i am working. How else do i demonstrate my professional requirement for the course?

The training is scheduled for 24 of this month. Do you think i can re apply with more documents as evidence? What chances do i have to attaining the visa within these days?
