I don't think so. Mame can do it, however:
Checks for invalid or missing ROM images in your software lists. By default all drivers that have valid
ZIP files or directories in the rompath are verified; however, you can limit this list by specifying a specific
driver name or wildcard after the -verifysoftware command.
So I'm thinking that it might not be hard to implement, in QMC2. But execution might take a very long time, which is why I suspect that option is not available.
I also think startup time (always a concern) would be significantly impacted, reading in a huge sl state cache. So better to just check the roms in use, between sl updates.
I don't mind hitting f10, if/when I decide to play some new sl. I'll admit, though, once or twice, I have also thought: "Wish I could do them all, at once.".
