Option to customize Privateer Ships

Selecting this option allows the player to save one configuration per mercenary hull. After that, the player can select any number of these saved hull configuration to create a fleet, on an owned system to deploy it. This fleet order should be limited by the player current maximum CP

This option can have an additional cost in turns and dust to balance from normal Privateer units, and made unable to retrofit

This request option could look like this:
