Allow number of digits generated by ${NUM} to be customized

[Easily to verify and replicate ...]

The ${Num} only allows 6 digits. It does not allow a place to change it on the non-Expert version, such as the TAB:Output/SECTION:Preferred Output File Settings, like a counter-box to enter an integer – for size of Number-Field.

You can change it if you click on Expert, because it defaults to 6 on the last tab. But, I tried that multiple ways, and changing it did not affect the size of the ${Num} field on the filename created for the output.

This is very easy to verify and to replicate. PLease fix by allowing a field to set ${NUM} size and maybe allow the setting of where it starts (such as 1000, 100, 0, etc.).
