Auto numbering in custom sequential patterns

I have an email here from PowerObjects saying it can't be done:

"Hi Michael,

The way PowerAutoNumber currently functions, it gives you a unique number, but it only increments by one – so 10001, 10002, ect. You can decide what the beginning number is and it will increase by one from then on.

Please let me know if you have any other questions.

Thank you!"

I need something that can go in 0010,0020,0030 etc.

I've always used the CRM Innovation AutoNumber solution, and although I've never needed to increment by anything except 1, I think AutoNumber includes this feature.

Hi Michael,

Well, I guess I could have read your Email a LITTLE more closely.  Sorry about that.  I checked with our team, and indeed PowerAutoNumber doesn't do an incremental string like that. Let us know if Neil's suggestion works; otherwise, you might be looking at a plug-in or custom workflow extension.

Well as it happens that the amount I need to increment by is 10 so I can just use power auto number to do this. If i want a 5 digit number going in 10 I can just have: {a:4}0. That way it will look exactly like its going in increments of 10, although this trick wont work with anything other than 1,10,100,1000 etc.
