Ability to add a graphic pack to a station

Building your stations in a large city like LA, You have to work with multiple departments such as LAFD, LACoFD, and other smaller departments.
It would make it much easier to customize the graphic packs of say, LACoFD vehicles if you could just assign a graphic pack to a building instead of having to go through and manually change every vehicle.
It's a small thing that of course isn't really required, but I think for people who try to strive in realism per department and have graphic packs for multiple departments it could make things a lot easier.
I'm not a game developer but I doubt it would be that hard to do, since, you can already do it to a single vehicle.

Oh, now I feel stupid, sorry!
