Can you: Build something without the building unit moving to the location?

Is there a way to make a unit build anywhere without having to move there?
What I am trying to do is have a unit that can not move be able to build something in another location. Actually, what would be better is if there was a range on it, so it could only build within a certain distance of itself, which would work to keep players in their own areas.

Try increasing the range on repair-human (it's a human unit ability).

You could make dummy abilities based off of abilities that target points, like Wards, and cause the buildings to be constructed via triggers.

The problem with using abilities, is it just doesn't give the same effect, like the model showing, but what I would do is give the builder all the buildings to build, but via triggers cancel his order, check the range, and if it is in range have a dummy unit build it.
