HelpStudio works perfectly when two users are documenting two different topics concurrently under source safe control, because each of one check out their topic. But when those topics have widgets, there is a problem, because both users need to check out the project file. Is there any solution to it...

We are a subversion shop, however the subversion integration is not really available cleanly so we are using Source Safe. Is there a way for multiple check out and merge of a topic? I hae SS setup to allow for multiple check out, but Help Studio does not seem to respect this.
