It would be nice to have same functionality for hiding some layers from layers list as it is in Web AppBuilder.

For example, when I add Tiled Layer, which is generated from one layer, I still get second subtitle. In the picture - Tiled Layer "Lesní biotopy" is generated in ArcGIS Pro from one layer "Lesní biotopy". I want to get rid of the second subtitle, because it is confusing in layer list.
