Including EDI Vouchers into Approval Workflow

Hello,

We are currently upgrading the 9.2 and I would like to ask if is there a way to include EDI vouchers to pass through Approval Workflow without someone clicking the submit button for approval.  The functionality is that the system will push the vouchers for approval to user's worklist if a certain criteria is met.  The business is loading thousands of vouchers on a daily basis and would want to route the vouchers directly to the worklist.

Any help or responses are greaty appreciated.

Thanks

Michael
