Calculated field from other fields in pivot table excel

Question

I have this pivot table that is showing distinct count values. I cannot change the data base source so I need a calculated field to group the indicated headers below

For the purpose of my analysis ASW, BSW and SW mean the same thing. So any time the calculated field sees that any of those headers has a 1, it should throw a 1.

Answer 1

I've found a way by adding a new conditional column to the query.
