Action groups and KAL-1000 can't operate docking ports

[RocketSquid]

In trying to reinforce the engine connections on a tiltrotor plane (the engines kept flailing themselves into VTOL mode during normal flight) I came to the idea of using docking ports. It works perfectly except for one problem: neither action groups nor the KAL-1000 controller can make the ports undock. The only way to do so is through the PAW. I'm wondering whether this is a bug with the game, or something I'm doing wrong.

You could try enabling staging and then set them to stage in an action group. I have no idea if any of that would work but it's worth a shot I suppose. I can think of at least 2 things that could go wrong. Staging may only work for actually staging, and won't undock docked ports later. Also, staging may not show up as a thing to add to an action group.
