Cascading Group Filters?

[Fendley]

I’m using ArcGIS Enterprise 11.5 with the new group filter widget in Experience Builder. I’d like cascading behavior so that when I select a State, the County filter options only show counties from that state. In the standard filter widget, there’s an option to “List values based on values filtered by all other expressions”, but I don’t see this in group filters.

Is cascading supported in group filters yet, or planned for a future release?

Turns out they can, but you have to set them up in separate filter widgets. 
The customization of the filter display is dreadful, but it works.
