Attack group management - HOWTO?

[Umrug]

Hello!
Minutes before I start writing my own Helper AI or LUA Widget - I decided to ask here.
I need to manage an attack group: lets say 4 bulldogs, 2 penetrators, 1 Seer, 1 Phalanx, 3 combat engineers. I need to send those guys into an attack with following limitations:
- all move in the same speed exactly
- stay in the formation I've initially assigned them to (tanks first!)
- don't move forward until everything in the range of penetrators gets destroyed (I'm in no hurry). OK I'm ready if it'll be "range of all land units"
- Can rotate while keeping the formation
- If possible (here I'm going a little overboard with my requests, I know) that engineers repair broken units (yep that could probably be done with guard area-repeat)

Don't yell CTRL-Move on me, since it does not allow rotating, and I have yet to see a straight attack path.
Also, I didn't get what "SimpleFormation" Helper AI is good for.

ANY help and ideas will be greatly appreciated.
P.S. I don't understand how do you guys get along without it for so long. The game urges for that!

That's completely not possible yet. You could try simply microing the group, though.

right click dragging move commands ftw.

However i think you really dont realize just how much work that will be as itll require an entire pathfinder to pull off, making the groupAI slow, and the lua version a nightmare to code as well as being even slower.
