V9.14 (Game is running nicely in the image).

Could the group button have a two-way function, that is: deselect the group without choosing a destination?

Suppose after selecting the group, I change my mind, and want to leave this force in position.

There is no way to deselect the group at this point in the actions. I now first have to select a destination tile for the group. Then I have to deleselect the movement of the group, for each unit individually. Ony then I am back where I wanted to be: not move the group.
