How about a new special CV block that can be used to build landing pads on or in CV's that will 'stick' an unpowered SV or HV to them.
Eg, build a pad of 3 x 4 CV Landing Pad blocks and then position your SV or HV on to that 'pad' and as long as 1 block from your SV / HV is touching 1 CV Landing Pad block AND the SV / HV is unpowered, it will stay stuck to the pad. Then the CV can fly around with the SV's / HV's safely parked.
Maybe add an indicator lamp to the SV/HV cockpits to show...
