Hi there! There currently isn't a mode in the Faderport 8 or 16 that has it automatically following the track selection. I'm hoping they add it soon.
However, to save you banking over like you described, with the Bank button enabled on the Faderport, you can simply press the large encoder down and it will jump to the bank that has the highlighted track. I do this all the time. Select a track, tap the large encoder, and bang, I'm there. Hope this helps!
