Negative Range Value for the Move/Copy Parts (6) Rule

[spacev2]

When using the Move/Copy Parts (6) Rule, I find situations where the positive range value for the "To Start, To End, To Pos" doesn't line up correctly in the file name (across multiple selected files). However, if there was a negative range value where the user could move or copy a part of the file name and move it backwards through the file name with a negative value position that it would line up in the correct position of the file name.

This would be a useful feature in my opinion.

Thanks
