Can't find selection groups logic.

[micheus]

I have a stored selection. I want to subtract it from current selection.

Checked in 2.0.3 and it's there.

With the current selection; go to Selection Group window; Place (not click) the mouse cursor over the stored selection and in the context menu (right click) you must see the option Subtract Group;
After that, the current selection must "exclude" the elements present in the stored selection.
