Add a map service to a map dynamically as a user?

Is there a way to add a map service to the existing map in Web Viewer as a user that is not selecting one from Portal/AGOL? Could a workflow even do this? This was requested from a funder to match Essentials functionality in the previous tool.

  Hi Marc, 

  A workflow could do this, using an activity from the ArcGIS Maps SDK for JavaScript workflow activity pack and and a VertiGIS Studio Web command in a workflow.

  Below is the JSON for a very barebones proof of concept workflow that adds an AGS layer from a URL entered in a display form to a VSW app. You can save the JSON to a file and upload it to your Workflow designer.
