Feature request: Adjust altitude during WP mission

Would it be possible to implement an altitude adjust feature during WP missions? Ideally it would be great to set this up on a 3 position Tx switch whereas each time the switch is momentarily placed in the high position the mission altitude is increased by 1 meter or decreased by 1 meter by momentarily placing in the low position. This would come in handy in the following scenario: During a low level terrain following survey mission the drone is approaching an obstacle. The pilot could “bump” the altitude up 3 meters, clear the obstacle and then bump back down 3 meters continuing the mission. Thanks!

You need to post this on one of the other categories. As it’s a firmware change not a mission planner change

Thank you, I will post this in the copter category.
