How to choose ANT+ over Bluetooth with dual sensors

I have a Viiiva HRM and now a PowerTap P1 PM that both have Bluetooth and ANT+ wireless. I really want to use the ANT+ on both devices but the 1030 only defaults to Bluetooth. Since I haven't figured out how to turn off the Bluetooth I can't connect with ANT+. The P1 is especially important because I don't see left/right power balance when using Bluetooth.

Any ideas?
