I like to approach stations as modules:
Like a main section, possibly some cargo, some extra fuel, abit of ordnance, some shuttles. . .
Then depending on what type of Station I want; just tractor other station bits on 'Recreational Space Telescope', 'Fuel harvester array', 'Maintenance station mod' and ofc. . . military platforms/stations(Built from shipyards) like weapon platforms, fighter hangar, sensor platforms, PD platform' etc. Slap it all into one group and call it Station X. Modular space station, compromised of bits and pieces of civilian and military gear. Abit mjeh to tractor around all the bits to, thankfully don't move stations to often
