Auto Base Setup
You possibly can confer a Special Group Status on a builder group. You can pick a Layout template [aggressive/resource/neutral/naval/airbase etc] and set the group off to the spot using waypoints - with the 'build here' new button as final waypoint.
Whilst they are moving you can use the Building Plot idea to allow a base layout to be set whilst far from the area - with it following the directions as best it can when it gets there - with you online/offline. A transitory menu showing active one off commands and macros could also be useful here.
As to the layouts - I'd have set basic ones and allow custom ones also - maybe 10 slot layouts options - again - with a separate layout manager maybe even third party outside of client, or even better - if client and such apps could communicate and plugin direct!!
