Composite Layers in ArcGIS Online

[MelanieRosenberg2]

I would like the ability to create composite layers in arcgis online based on other items in my arcgis online content. For example, I would like to create a layer that includes specific fields from separate tables as well as a spatial layer in my content. Essentially, I want to mimic spatial views or query layers, but based on hosted items in my content (that may be part of separate services).

I agree 100%. We have many hosted feature layers that are stand alone services, but we'd like the ability to "group" them into a single "service view" to present access to them through a single rest endpoint. This would be a tremendous benefit for integration with other applications.
