How to add legend to custom print layout with print dijit params

I have a custom widget that allows the user to enter a query string and select a field to symbolize the selection set by unique value.  I want to pass the unique field values/symbolization to the legend of a custom print layout template.  The attached image represents an example of a selected field, unique values and their symbolization (This is what I'd like the legend to look like).  This is what I would like to pass to a Legend element I have in my custom print layout template.  I can pass text elements with no problem, just can't figure out how to pass a legend item.  I'm using the print dijit and set the "templates" param to a variable that contains info pertaining to that specific layout.  I see there is a "legendLayers": [], param within the layoutOptions; however, I can't seem to get this to work.  As I mentioned, I'd like the legend to look like the attached image.  Does anyone know if this is possible?  Any help/suggestions would be greatly appreciated.
