Hi Mario, I have some good news.
>Sadly, it seems like you can't select a subdomain in the subdomain mode and carry that selection to
>boundaries or edges (that would be a great feature).
We added this feature to version 4.0, to be released soon. A lot of other good stuff with repect to selection and model management has been added. Go to any of the COMSOL conferences if you want to know more and try it yourself.

I sometimes run into the same problem, especially with complex trusses.
As far as I know, there's no quick and simple way of doing it, but there are a couple ways to make it easier. Sadly, it seems like you can't select a subdomain in the subdomain mode and carry that selection to boundaries or edges (that would be a great feature).
As Ivan said, use (and abuse) groups. Normally, whenever I add geometry, I try to put it in groups as soon as I model them, and try to be very verbose about them.
Another good option is to use the boundary list in boundary settings. Get a feel of how COMSOL arranges them (basically, it starts at the origin and starts sweeping through the axes). Once you are comfortable with it, it can become a very powerful tool. It's been a lifesaver for me.
