TL;DR
Extend the functionality of the upgrade planner to upgrade buildings from an empty slot with modules.What ?
Pretty straight foreward, buildings and beacons should be automatically filled with modules via the upgrade planner, without prior manual insertion or via bp-workaround. I suggest to use the empty slot on the left and [module] on the right in the upgrade planner interface.Why ?
Upgrade differnt tiers of modules or building is sufficently coverd by the upgrade planner. Arguably to module buildings up, is upgrading them to. Besides manual placement or an akward workaround with a red- and bluprint, the process is insufficently automated. Although being a rather edge case scenario, the upgrade planner moduling could be a great QoL. Esspecially in later game with e.g. bulk amount of yet empty miners waiting for some modules. As plus the inferface wouldn't need to be alterated.I can't think of any other "blank upgrades" then for modules, but maybe I'm overlooking something.
