So currently you can order custom production from your faction that you can use for yourself. I just wish there was ability to give these ships to your allied patrol fleets. For example if I have a ship I have salvaged and I do not need, but do not want to sell it cause ships are cheap to sell currently. So I would want to give away this ship to be used by my fleets, I know that currently allied fleets spawn automatically based on doctrine, but it would be cool to manually customize them at least this way.
