Spring RTS Engine

Would it be possible to achieve fast access to unit commands?
Problem is that when you try to check commands to see if you can drag them with a waypoint dragging widget,it slows the game down terribly.
Can some thing be done about that?

Another thing is to allow not to draw individual movement lines of units.
What I mean is that if i select a group of patroling planes only a general patrol route would be shown instead of all the lines coming from all the planes as they move to the next target in their patrol move orders.

what?

What was unclear? :)
first part addresses to the slowdown you get with a waypoint draggin widget when you have big groups of units selected since it needs to check all the commands and it happens very slow so can a faster access to unit commands be achieved with ptach to the code or..something.

second part addresses the fact that when you select a group of units
and press shift it shows each units individual command lines.
If a goup of planes is in patrol and you select that group and press shift you will see each unit has a movment line drawn from it.
Im asking if something can be done to allow not to draw each units individual movement or patrol or attack or any other command line,
and instead show one single line for the entire group to not create clutter on the screen in a busy game.
