Allow Portal custom print templates to be used in ArcGIS for Excel

[andrewdc_tt]

ArcGIS for Excel has a print option that allows a user to a variety of default page layouts. It would be great if were possible to print to custom layouts as well - that would improve the quality and standards of our map outputs.

For example, our ArcGIS Enterprise Portal default print service is set to a custom print services, which points to a print service containing custom layouts (with a logo, titles, custom text elements etc.). Ideally when signed into Enterprise with ArcGIS for Excel, the default Portal Print service would automatically be available as an option to the user, and display the requisite custom fields the print service supports in the UI.
