Create a Calculated field based on tag field and use in Filter

I need the ability to look at tag fields like arrays for calculated columns so I can filter tags as a combination of values

Example:

Create a calculated field
count([self.features tag == “TEAM1”]) + count([self.features tag == “TEAM2”]) + count([self.features tag == “TEAM3”])

Then allow that calculated column to be used in my filter, then I could select the returned value of the cal col is greater than 2, then I can see if features or epics have more than 1 team assigned.
