Ground Control Software Mission Planner

Hi All

I am trying to plan a mission such that the wp is 100m below my home altitude ,
when i try to enter -100 in the altitude column MP says

“Please reduce altitude warning …”

Kindly help me , Michael Oborne and other fellows how to achieve this mission.

Question # 01:
Can i enter negative altitude in Altitude field in mission planning?

Question # 02:
Is there anything relative to “altitude warning”

After searching i finally get my answer

" It’s the alt warn box above the list of waypoints.
Just set your limit Say -100 and then you can easily enter negative altitude."
