I've noticed there are many variants of Mushihimesama Futari, and while I'm interested in v1.5, I'd hope to also be able to run Black Label at some point, of which the option is not available; as such, I'd like to ask if adding categories for game version is an option.

Just throwing it in there that Black Label has been added as a separate game for anyone interested:
