I'm setting up an Operations Dashboard (Enterprise GIS 10.8) and attempting to set up a filter on a map whereby one of the map layers will filter based on a selection from another item in the dashboard.
It appears as if I can only filter on layers published with Feature access enabled. (If I needed to filter a 'vector' map layer, I could just modify the service to include Feature access. However, I would like to filter an image service layer.) The filtering capability works in the portal map, so I know the server can see the underlying footprint attributes. I was looking for more details here:

without luck. Is this possible, and I'm missing something, or is it not possible (and I need to put it in as an enhancement request)?
