In an MEP workflow there are repeated things you do all the time and they take lots of clicks.
An example: In an ELEC model, you need to turn on the architects model to see if they have placed electrical fixtures. To turn on the arch model's fixtures you've got to edit your views VG settings and go into revit links, arch model, custom, model groups, turn on electrical fixtures and then make sure the workset it turned on. Then you need to jump through ten hoops to get them to show up in another color.
There should be a button that toggles on and off the arch model's fixtures/ lights/ etc.
