For what it's worth, I'm doing the same thing with grouping versions of games under one game listing to reduce spam or duplicates, and I've found that the best way to do this is by using powershell or .bat scripts. I tell Playnite that my script is a Play Action file, meanwhile I have my script launch the correct emulator and ROM combination. I admit that it's a little tedious, but it should be fine if you have a curated collection.
