I would like to add Bing Maps as a base map using the WAB Basemap Gallery Widget. Currently I have added it to my web map via AGOL. When referencing that map in WAB it loads with that base map intact and it is part of my gallery. However, this requires that the Bing Hybrid loads as default at start up. It also makes it a pain to manage my web map as I have to remember to add Bing each time before saving.
is there a way to add it directly to the basemap gallery in WAB?
