Lot traits needed

I'd prefer they completely do away with lot types and make it like Sims 2 where you can have multiple lots types on one lot and they all work like a restaurant with a bar and a underground bowling alley would be my style of game play I hate being limited to just one. Now being able to have lot traits used as a tool to customize these lots would be nice like a teen only lot or maybe a lot type that makes a Sim flirty all chosen by the player.
