Its a pain to keep switching your tracking back and forth. The only real way to successfully do this is to get one on a second toon just for the tracking.

For example. MIning and Herbalism on main toon. Main toon keeps Track Mining Node turned on
Herbalism on Second toon. Second toon keeps Herbalism tracking on. He doesnt gather hes just a tracker.

just make sure you have a good view at the 2nd accounts mini map and you'll be good to go.
