How to pause landing my VTOL plane?

Hi there:
I found it useful adding a pause landing function while my VTOL plane auto-landing above an obstacle(like a tree).
1. Is it possible to switch to QHover mode to hold the height and move the plane horizontal by joystick? I try doing so but my plane keep moving backward after switch to QHover mode.
2.Since the “abort landing” button doesn’t work, maybe recompile the mission planner and add an “pause landing” button could be a possible way?
