You can separate them.
Since the majority of the orders that a Squad leader can command will bee attack/defend flags on a map, you can enable simple commands inside the menu settings. Still use the spot key (for me, it is D) and just hold it when you are looking at a point/position/flag, and use the circular menu to issue a command to your squad. Works a lot better and introduces separate keystrokes that will differentiate between spotting and issuing a command.
