Remove Change notes on Workshop

[fortun 14]

Have had a mission up and running on workshop for "Friends Only" to help testing. Have done like 20 updates to it that is small and without any Note added.

However, it seems to have created also 20 Change notes on my mission which i can't find how to remove before i set the mission as "Public for everyone".

Would like to remove all those old Change notes on the mission before, so it looks nice and clean. Is the only way to do this to remove the mission from workshop and then upload a new one?
