Was wondering if you can change the way fleets are built in the game? By that I mean if you can remove the build option for all combat vessels in the frig factory, then make it so that each cap ship is built starting with a full fleet of preset frigs and cruisers.
Each cap ship should have a fleet preset that is filled with appropriate ships both supporting and attacking. The build times should be pretty long and cost very high.
So is that possible ? Anyone working on something like this? If so please let me know

Edit:
This is probably a long shot. But can you set it up so that frigs built in a sector cant leave it? If so it could be set where the frig factories can still make frigs, and just make the cap ship/fleet cost a command point but not fleet points. This way you can still build ships with the factories but only for planet defence. The fleets would be the mobile strike forces, used to capture and plunder,so obviously would need to be pretty big.
