Does Casa outback failsafe work?

#1

I’m trying to make a system (based on 1.8.0) that has more advanced Data link loss behavior.
Instead of just RTL. I would like it to go to a point and wait for a configurable period of time and THEN return to home and land.
Is this possible with the CASA outback challenge failsafe? Does this work on 1.8.0?
