I haven't been able to find this in a forum message, so hopefully it's not redundant (or already possible)...
In operations Add(7) and Numbering(10) I'd love to be able to specify target locations relative to the end of the name string, either by...
1) Allowing -ve insertion values; or,
2) Using a new numeric cell.
I vote for option 1, because no additional UI layout work would be needed.
Thanks for this tool, Mr. W!
