AUTOFILL RESERVOIR
Autofill would be much more pleasant if you could decide to allow it or not. For example, let's say I decide to fill 5 games in a row. Now, for the next 5 maybe I can use this "reservoir" to get my 2 preferred roles. I hate the helpless aspect of autofill and having a choice would make it far more tolerable even if I get filled the same amount of times.
