I am using Nintex Workflow 2013 with Nintex Forms 2013. My users are accustomed to using the out of the box SharePoint workflows in our Moss 2007 environment and they rely heavily on the "Request a Change" and "Add or Update Approvers" functionality. I have rewritten their solutions using Nintex forms and workflow and I was able to provide the "Request a Chagne" functionality by creating a state machine workflow. They are now requesting the ability to Add or Update approvers while the workflow is in progress and I have not been able to figure out how to do that.
There are several approvers that I pull from a lookup list and the tasks are assigned one at a time by using a foreach loop. How can I provide the ability for them to change (add or remove) the approvers once the foreach loop has already started?
