Comment 3 for bug 700877

No, I don't think there is an option.

Are you interested on working on a patch for this?

I think we would have to default group names for old files to match the old "group%d" naming though, to avoid breaking anyone's processing scripts which rely on the existing file-names.

We would need to extend the file format to name the groups and introduce some data-structure in PCB to store the naming.
