I needs some help with a workflow item.  Our current account numbers range from 3 digits in length to 6 digits in length and I want to keep them a consistent 6 digit format in Laserfiche.  For example account number 100 would be 000100 and account number 10000 would be 010000 account number 100000 would stay 100000.  I was wanting to build something into my workflow to validate the account number length and modify the account number if it does not meet that format requirements by adding leading zero’s.   Is this possible using a pattern matching token?  Once it is in the correct format my workflow is already set to file in the appropriate subfolders.  To this point we have been relying on employees correctly putting in the account number in this format and I would like to automate that if possible.   Thanks!
