Changing build range - Possible?

Does anyone know if, and if so how, it is possible to have buildings build other buildings at an ulimited range?

The hidden 'Build (Race)' abilities don't have a range stat to change, so I'm currently stuck with using abilities based off the 'Tiny <building>' items - The problem is that those have no gold cost, and a triggered cost system doesn't look as good as the original.

I've managed to give building ability to buildings, but range is still a problem.

If anyone knows of a way to change the range for building, please answer.

You can change it in gameplay constants. However changing it there will affect EVERYTHING, even the "build tiny..." abilities.

Really? I've looked through the gameplay constans many times, and I can't seem to find any such value. Mind telling me what the name of the field in question is?

Whoops sorry, I did research about this a long time ago and i posted that reply at 7am my time so i was a little confused. What I should have said is that you can use the "Build tiny..." abilities to build the secondary buildings. If you don't have enough space in the command card, you can tie it to a spellbook ability.
