Transit Qatar visa by Qatar airways [closed]

Me and my girlfriend, both we need a transit visa to enter Qatar and our passports are not eligible to do it on arrival.

Qatar airways offers a service to make it for free. Cool. But the problem is that we'll fly from different countries so we'll not have the same ticket and we need to apply for a visa separately. I think that our chances to get visa is greater applying together than if visa officers see that my girlfriend goes there along.

Could someone who has already applied for a visa through Qatar airways tell me if there is a way to link our applications together.
