I am wanting to create a table on the server that will be populated with a workflow.  the workflow would look at this usertable and then match it with folder names to create a list.  I have a folder with client names and I want to create a dynamic field on templates to reference this table so we are always filing to the correct client and not duplicating.  I am comfortable with creating the field in templates and linking to server usertable.  

I am having issues with getting the workflow setup to populate the table. 

Thanks.
