787 Logitech Multipanel Heading select (ie. Heading hold off)

Howdy, first post here. Have trawled the forums with no luck so am posting this question…

The 787 Autopilot ‘heading hold’ can be removed by pressing the select button, and then rotating the knob to the desired heading.

Now my question is, how does one assign the pressing of the ‘select’ button to the MultiPanel using SpadNext? Surely someone has done it? Or is there nothing for it?

Basically I just want to remove the heading hold using the physical control!

It’s possible. I figured it out through trial and error using Spadnext.
