I have four MP40w's and one MP10w linked wirelessly running Tidal Swell Mode. I want to add two more MP10w's to the group. Can I program the two additional pumps into the group without reprogramming the five other pumps, going through the clear driver memory, configuration mode, assigning master /slave and resetting master pump to each of the pumps as implied in the manual. Seems like a lot of work just to add two additional pumps. I don't have reeflink so any answers have to be for the old fashioned button methodology.
