Automatic stamp with workflow???

HI All.  Does anyone know if it's possible to add a stamp automatically with workflow?   I have 8 to 10 documents per group of documents. (HR documents for Employee with EmployeeID not empty and Status field =verified.  I would like to manually stamp one document in the group after verifying, which kicks off my workflow.  The workflow would look for the documents with the matching employeeID and a status=New and stamp each of those documents. 

Can anyone shed some light if this is possible.

Hi Michael,You can add a stamp independently of workflow tasks using the SDK but there's currently no other way

This idea has been present in the uservoice forums so I'd encourage you to go vote (I have, it's a great idea): https://docuware.uservoice.com/forums/230572-configuration-english/suggestions/32295130-workflow-designer-request-for-a-new-activity-st
