How to Make Space Doors (need advice)

[Mister Dilsby]

Working on a little something called a spacecraft carrier and have what I think is a nice solution for carrying a Mk2 spaceplane internally. Asking for some help from the mod community for how to make deploying the doors a little more easily.

Here's the carrier with the "space doors" for the internal hangar midway through the 'opening' operation...

The doors are six stock CRG-25 short Mk3 cargo bays. To "close" them I set the Deploy Limit to 50, and to open them I set it to 100. In the picture, all the doors are "closed" except for the center lower one which has been set to 100 and is "open"

And here they are opened,  (deploy limit = 100) with my spaceplane backing into the hangar deck:

...and a portion of the config file for that door:

    MODULE
    {
        name = ModuleCargoBay
        DeployModuleIndex = 0
        closedPosition = 1
        lookupRadius = 1.5
        
        nodeOuterForeID = top
        nodeOuterAftID = bottom
        nodeInnerForeID = top2
        nodeInnerAftID = bottom2
 

So what I'm wondering is this: can I change closedPostion or one of the other parameters such that when I trigger the "Close Door" action it goes to the 50% deployed position? This would allow me to use Action Groups to toggle the doors to the open and "closed" positions as i have defined them. I already tried setting closedPosition = 0 and that didn't seem to do anything. Will be grateful for any help, thanks!
