I would like to see that it's possible that I can manually disable flight features of fleets.
Simply I want to send providers from 2 different planets to the same location with both being able to return to the planet they were send from. This is currently impossible because I can't overcome the flight features which "fuse" the fleets together.

send them with gas and switch off return
when would finish collecting,   send the fleet as you like

It would be a lot easier if it's added to the same options menu where you can select to not return your fleet when there is no debris anymore. Just that more fleets then get the options button.
