Varia Vue, RCT715 & Edge set up

I have had Edge 1050 and Varia RCT715 for about 9 months. Just added Varia Vue. Two things in the set up I am struggling with, they may be related.

1. I want to have the Vue recording continuously and the RCT715 just on radar activity. But its seems something overrides this and both cameras are recording continuously.

2. I want to have both cameras battery status showing on my data screens. When I try to add them I can only chose one, no matter how many data fields I try.

Anyone know how I can set this up?
