Is the ability to host a tiled mapping feature service on Portal for ArcGIS (10.3.1) available as it is with ArcGIS Online? I ask this in relation to hosting a tiled map service for the purpose of taking this tile service offline as a basemap with Collector (10.3.1 Build 990). I see this functionality is available with ArcGIS Online/Collector 10.3 and I would like to take advantage of it with our Portal for ArcGIS. This is a great enhancement over the creation of TPK files and side loading for offline basemaps. Thanks for your input.
