You could open up the vts/hrc menu as though you are goug to order a unit. You could select the 'plus' and his the 'order' button (it would say something different than order though) and the menu would disappear. Then the next place you tap (not tap and move because you'll need to move your camera) would be the rally point. To remove a rally point you could go back into the menu, select the 'plus' and hit the 'remove point' or 'remove rally' button.
What do you think of that? Maybe to do it quicker, the button could be nect to the sell button when you select an vts/hrc.
