Is there any way to script the creation of a dynamic group with it's filters, etc.?

I can't see anything in zman, but perhaps I am approaching it the wrong way. I seem to remember something with registration rules and xml files, etc....

We have 150+ groups to create and the info required is in a spreadsheet.... with a bit of textpad search/replace, etc. I have performed similar tasks in the past, given the required commands....

Cheers
