Can I get a single undock button for a multi-size port?

[Galane]

For example this. Dock two of these together and to undock it has to be right clicked and an undock button clicked three times. I'd like to be able to have a single button undock any number of nested ports, two, three or four, no matter which combos are docked. Maintaining the ability of docking mis-matched nested ports or single ports to a nested port is also desirable.

description = Invented after a less-than-peaceful protest against the lack of spacecraft attachment systems that could make buiding multi-purpose symmetrical bases possible, the Clamp-O-Tron Omni Docking Port allows for the firm attachment of two separate vessels regardless of the other dock's type. After docking, vessels can be just as easily undocked.

Hey FYI I have released universal docking ports here. If you're building your own then talk to toadicus here. I'm using his plugin. It allows a docking node that changes depending on which size of docking node is nearest and then docks to it in the normal way.

Oh and yeah, it only gives you one button.

I guess I should make it clearer in my signature.

I'd like to do it plugin-free, keeping with PolecatEZ's original ReStock that's just cfg files that adjust and blend together stock parts.

[CaptainKipard]

Well you can't, not if you want the docking port to attach to various sizes with just one button for undocking. That's one of the reasons toadicus offered to write this plugin for me.
