Zero indexing

[RasmusAPedersen]

Thanks a lot for this plugin! Makes it a breeze to have sequential part numbers.

We use a system that goes:
123-456-7890

I would build this like so:
{1+}{2}(-){3}-{4}

This means my first IPN would look like this:
101-001-0001

Ideally I would like my first IPN to look like this:
100-000-0001

Is it possible to change between zero and one indexing with the current system? I couldn't quite figure it out, which makes me think that it's not. If it isn't possible, it would add some nice flexibility to make it possible.

Thanks!
