Using a geocode service in a Display Form autocomplete (Workflow 4)

I'm trying to figure out if it's possible to use a geocoding service in an autocomplete box in a Display Form. The use case is to have someone search for an address in a form and then use that to determine the location to place a new job.

Right now I can have the user use the global search bar to geocode first, then right click and invoke a workflow, but that's kind of clunky. Any way to have them do the geocoding step as part of a Display form to save some clicks?
