renaming file with a number

I would like to use Hazel to rename my monthly receipts and if the file already exist for that month add the number 2 or 3 to the file name.
For example if I make 2 payment to my credit card that month I would like to have "jan CC.pdf" and if there is a second payment for that month I would like to have "jan cc2.pdf" and have hazel add that number but only if there is a second payment for that month. The following month this would be repeated for example "feb cc.pdf" and "feb cc2.pdf"
Can Hazel do this?
