Select all on mission editor wanted

[SilentHunter]

Sorry if duplicate did not see it mentioned. In the mission editor did not see a way to select all or a range of units. Having to click all units to assign them and then click them again to assign them to mission is a little tedious. I realize when creating scenarios this would not be useful but for us beginner mission editors just playing around a select all button would be great. Low priority in my mind.
