Change track icon intensity for multiple tracks at once

I’m a big fun of Media Bay and I save tons of track presets to be reused in various projects. I also set up track icons in those templates.

However, when I import those tracks, sometimes their track icon color intensity might be different from the intensity used in target project. Changing the intensity manually for each track is quite cumbersome and some kind of system for doing it in bulk for multiple tracks would be welcomed.
