Export file name

Hi!

I was exporting an album from InDesign to individual JPEG files for each page and when i name the the first page as 01, InDesign instead of naming the second page as 02, it names the file as 012 and by the twentieth page the name will be 0120.

Is there any way so the files will maintain the order from the first number i use and maintain the same numbers of digits?

For example if set the export page to be named as 0004 and all the others pages will follow this sequence.

Thanks
