Okay, I have my platoon scattered. Now, I put my HQ up in the Church steeple to spot. However, I still have one squad that has a ways to go to reach a defensive position.
But when, my HQ are inside, I cannot issue a RUSH command. So, I have to UNMOUNT them. Then, I can issue a RUSH command. One of 0 meters. Thus, I only need to adjust the squad who is out of position with yet another RUSH command. Then, I can MOUNT my HQ back into the Church.
This must be a version of the Hokey Pokey for war gamers.

If anyone knows a better way of doing this, then please let me know. Thanks.
