Connect two sources: Unable to connect powermeter AND smart trainer

The Bluetooth connectivity seems better now, but I don’t see a way to select between getting the power information from my Wahoo Kickr and my SpeedPlay pedals. My coach prefers me to use the SpeedPlay pedals for accuracy and left/right pedaling balance. However, I need to select the Kickr to control the resistance only and not resistance, power, and cadence.
