Does PA have default move orders or a way to keep units at standoff distance?

I am having trouble keeping my combat support units at standoff distance. They seem to want to charge the enemy unless set not to move. individually or in groups, having to change move order is a chore and just one more thing to micro.

any suggestions?

lazy unit ai means you have to do it.

Everyone:

Before forming an opinion on this matter, I'd ask that everyone play the free RTS Zero-K, a game that does automation very, very well.
