grouping assignment groups and using in interactive filters

[Elizabeth10]

I need to create an interactive filter that has :

All Tech hub (list of 30 assignment groups)
2/3 level (list of 50 assignment groups)
ServiceDesk ( list of 6 groups)

I don't want the actual "list"  to be shown I just want to choose "all tech hub", "2/3 level" or "ServiceDesk" and the reports will update based on the groups contained in these.

How do I do that? I have tried with "group" and "cascading" but can't get it to work as I want

Hi @Elizabeth10 

I think it can be done this way, as these are filters, and the filter works with a specific value. We may either need to change the logic or consider the parent-child relationship of groups. In that case, it might work."
