That's a good idea, I'm just not sure how to do it. Unless you can add a couple of lines to the xml document to do that. I'll look into this, maybe it could also apply to Roman army camps, and German wagon encampments?
Is it possible for you to try nightly built version? (for that you'll need to install git and download our repo)
It might, but they might disable it silently if there is a well known bug.
