Please add capability to filter map service sublayer based in Category Selector's Actions.
The key to getting a map service's sub-layers to work with dashboard actions is to ensure the url being referenced is the map service layer, not the map service itself. For example:
use this:
https://sampleserver6.arcgisonline.com/arcgis/rest/services/Energy/Infrastructure/MapServer/0
not this:
https://sampleserver6.arcgisonline.com/arcgis/rest/services/Energy/Infrastructure/MapServer
