So I have an interplanetary ship I am current on a mission with. The craft uses supplemental fuel tanks that are designed to be attached to docking ports in orbit and then discarded en-route as fuel is expended. They work well, but leave fuel tanks drifting between planets in wide, distant orbits. While I normally clear up debris in Low Kerbin Orbit, I am okay with this given the literally astronomical odds against encountering any of this debris again.
Unfortunately, the tanks I dropped did not automatically change their type to "Debris", which is odd because they have no command and control parts. Normally I would switch to the craft, go to rename it, and manually change its type to Debris (which is what I do with rescue command pods or things I abandon on extra-Kerbin surfaces.) Since there is no command parts on these fuel tanks though, I cannot see how to manually rename them.
Anyone know how to change the craft type without it having a command part?
