This is for Nestor. I probably didn't explain what I was refering very well. In Multisim the Project view allows you to Add a File from the hard drive. This is what I was trying to say. It would be nice if this option was available in Ultiboard. That way if would be more straight forward and you wouldn't have to do all the importing and exporting to add a board to your design. This would come in handy if your design is on more than one board. For instance, I have a desgin with a Main board and another one I call a switch board. Having these together under one Ultiboard project would be nice without have to to do all the importing and exporting. This is just an idea, based upon your post, that I thought would make things a little simpler.
