Using MISSION_ITEM_INT to update single waypoint

Hi, I’m wondering is it possible to use mavlink message MISSION_ITEM_INT or any other way to update single waypoint instead of uploading entire mission that can be time consuming.

I tried sending MISSION_ITEM_INT with waypoint sequence id that I want to update, but I get MAV_MISSION_ERROR in MISSION_ACK. My guess is that autopilot is not ready to accept mission item.
Can you please help

When I set MISSION_ITEM_INT, MISSION_ACK returns an error message with type 14. Have you solved it?
