I don't understand your first question, but the difference between dashboard and normal playback fader is that dashboard controls the fader on the actual page on screen, and normal controls page independent. The identifier in a task with normal PB-F controls "Page"."Fader". So the 3th fader on page 13 has id 13.5... The dashboard Pb-F with Id 5 controls the 5th fader in the software, on the active page...
