How to move Basecamp settings/profile across machines?

I've got no problems moving my data around, and have taken to using Basecamp pointed at a database in a Dropbox folder that is thereby automatically shared across my desktop and laptop.

However, I've customized various activity profiles, program settings, etc. When I go to a clean install on a new machine, those are all at their default values. How do I share/export/move/whatever those around?

Is that sort of stuff contained in the Backup function? I played with it a while ago and vaguely recall that was just data, not settings. I will try later but home someone will know off the top of their head.
