survay mission with cylindrical virtual obstacle

#### Issue details
I wonder if it is possible to have commands to add virtual obstacles in mission planer. Becuase, I want to do a survay mission with these virtual cylindrical obstacles there. Thus, the mission planer will use the dikstras algorithm to avoid them.
Is these features available or not ?

The issue names no files, tests, or entry points. First determine whether Mission Planner supports virtual cylindrical obstacles and survey-mission path planning; completion would require an agreed scope for the commands and avoidance behavior.
