Easier way to dock rails (maybe creative mode only?)

[solarapple]

The idea is that you select a rail using C, admin load the blueprint you want to be docked, and it spawns docked to whatever rail you selected.

Actually a nice idea, but ships can have more than one rail docker. Which one should be used?

Dialogue window may apear asking exactly that. Or just an error message: "entity cannot be spawned due to multiple rail dockers".
OP idea is perfect for interior turrets.

Nice.
(I admit I can't seem to wrap my head around the orientations of cores and dockers on the build-mode attach function. I just want a forward-facing ship/turret...)
