Lot Zoning: per room
I am using some modded rugs that designate a room as a rabbithole. Is there a similar method for duplicating lot zoning, such as the Library, Gym, Majestic Vista (or whatever its called), etc.? I would make some combined venues, but the only way I know is to zone the lot -- which only allows one type, not multiples. Plus, I would like to add a library/study to a sim's home, where they could get the library bonus, a rec room where they can get the gym bonus, etc.
Also, is there a zone type of some sort that gives a bonus to learning to play instruments like the library gives to learning skills from books or the gym does to athletics from working out?
