RyanAir Flight Pooling My Own Baggage?

I'm flying with Ryanair on Thursday and I bought the leisure plus which already includes one checked bag of 20kg but since I am moving back home I had to book another 2 checked bags of 20kg. All well and good so now my total weight allowance should be 60kg right? I tried talking to their live "chat" which is the most confusing and stupid thing ever as it does not give clear answers to questions! What I'm wondering is:

Can I "pool" my own baggage allowance, so instead of having 3 suitcases each 20kg can 1 be 20kg, 1 18kg and 1 22kg ?

I know it's a stupid question but I just want to make sure, before I go to the airport!

Thanks
