Optionally lock channel if not 'selected' in track display

I would like to optionally disable the ability to change a channel when scrolling down the track list. It’s way too easy to change a channel when you’re rushing to scroll down. If your slippery mouse catches the channel number on an instrument, it’s not very obvious till you play something and your violins have changed from legato to trills. I did read the manual in case there was a way to lock, or freeze, and I saw somethng about freezing tracks but it didn’t appear to be what I was looking for.
