If you could snap your fingers and add something to DDA, what would it be?

a completely freeform faction camp system, with the ability to go "i want a building here, of this size and shape, made out of these materials" paired with the ability to declare "this building needs to be a housing/workshop/storage area, fit for these purposes", ultimately resulting in "my faction camp 'missions' are completely derived from the actual constructed amenities currently in service, rather than pure abstractions that have buildings as a side effect"
