Wisepent is testing version 3.1 (aka 4.0) of their software, which might be right up your alley.

3.1 is a COMPLETE rewrite of the 3.0 program and is visually amazing to look at. A few of us on this forum are beta testing it currently, and I would think that the bugs will be fixed here shortly, in addition to a few feature requests being added.
If you can wait, then I think this will be perfect for your purposes.
