Hi, 

I work in an instance where there are many groups from different parts of the business.

I would like to create a Visualization that uses the 'Incident backlog growth' indicator.

For other indicators I have been able to use the filter Assignment group > Is one of, but here I have only Assignment group > is, available. 

I'm looking for advice on how to update the operator and if possible, tips on refining OOTB data sources to a set of specific groups.
