Using Multiple Sets Referencing Assignee Tags in Reports

Hello -

I built two sets and tried using both of them in the same report. One was returning results, but I was getting an error when trying to add the second. 

I opened a ticket and learned when there are multiple custom sets referencing Assignee tags it creates a conflict, i.e., only one custom set can be used per report. 

Recommending a product enhancement to allow for multiple sets referencing assignee tags in reports. 

Thanks!
