More efficient switching using pictctrl

Hail

I've designed a nice UI using pictctrl objects as toggles.

I'm building my own setup and want to easily select the strip in my desk to control with my midi keyboard. i want a point and click operation, not a drop-down to select the device to control. i have control and note data coming in from a couple of different places, and I want to define the UI so i have as little clicking as poss to get the functionality.

I have this

It works fine, but this is a snippet with 6 strips, but i have 28 in the desk and want to avoid connecting the out of strip 1 to effect the toggle off of all 27 other strips for each strip in order to get a posh radio button. I don't mind this laborious task, but is there a more efficient way?
