let the thumb buttons advanced click HOLD DOWN the assignment.
as it currently functions: if i assign shift+middle click to one of the thumb buttons, then logi options only sends that as a quick-click even if i am holding the button down.

many programs require shift+middle click or ctrl+middle click to be held down in order to pan or rotate the 3d view.
i want to put that on one button but your silly software only sends it as one quick click instead of holding it down.
