That sounds like a good idea. I have done that.

I don't have one yet. But I hope to create one this weekend.
Right now replacing the VN combining with this new functionality will not work
as it scans the defs itself. Though I am moving all the def scanning to its
own function which should allow for the code to be more modular and allow for
the VN combining to work with it.
