If it is a huge issue, either place your most played games in a main folder and just scan them and place the others (that you play infrequently..I assume the majority of them) in another folder that you only open when you want to run those.
Alternatively you could just make a few bat files that run your most heavily used games:
Dolphin.exe -e "path to iso.iso"
