Maybe this idea is already posted some time ago, I don't know, but this is my idea:
Is it possible to make that when you want to submit a score you can select a system you created on, let's say your profile, other than selecting a previous score(Prepopulate fields by score) with similar hardware. Then you can make a few setups, like a SB-E setup and an Ivy setup.
Say if you posted like 10 scores with an Ivy setup but then made a score with SB-E, the previous score with that system is already gone from the list of previous results, so you still have to fill in everything. When having a system pre-configured you don't have this problem. you could even make a comment part where you can, for example, already fill in who sponsored something
