Solo Shorcut

Hey Folks,
Trying to see if there is a short cut here to creating a reaction for this functionality – I will be doing it for 16 tracks so will be a lot of work in this instance.

The script attached is a simple ‘Track Solo Function’ – when I press the Midi Controller Button it turns track solo on, but when I press it again it turns it off. Im wondering if I can set up the Controller or the Controller feedback so that when I press it once, solo turns on, but when I press it again solo remains on?

Tnx
