Not that I know of, but there are some possible workarounds.

1. v.net, as Markus said, is designed to make the connections. I find it 
can produce some odd results, but that could well be user inexperience!

2. If you can't beat a problem any other way, use v.distance with the 
output flag set. This will create lines connecting source to 
destination. Gee, I should have thought of *that* sooner for a problem I 
was working on a couple of weeks back!
