If you use an Assignment report so that everyone is the Assigned To person, you can use this EXIST filter I use all the time.
EXISTS:a:$$OBJCODE=USER
EXISTS:a:ID=FIELD:assignedToID
EXISTS:a:teams:ID=53583029001ab9cdfd03610c38b97007
You will still do the filters you do the same for your regular Issue report, but you will now get the added bonus of grouping things by Assignee :)
(Assignment object type is one of my favorite reports to use)
