Ability to customize print templates in WebApp Builder without needing ArcGIS for Server

Idea created by ljahn on Apr 29, 2015
    It would be helpful to be able to add logos and branding to map prints (print widget) in WebApp Builder.  Currently, the only way to customize print templates is to have custom templates (MXD's) reside on ArcGIS for Server.  For users only using ArcGIS Online (AGO) and not having ArcGIS for Server, it'd be nice to be able to accomplish this as well.
