Selectively removing columns from a Matrix

Good morning.    I'm want to add a new column called Planned to my Matrix

I added it to my Values

I now see it in the Total column as expected, but I also see it in the weekday breakdown.

How can I remove just the Planned column in the weekday breakdown?   When I click on Exclude, it removes the entire column (Total Hours and Planned for Thursday) 

FYI, I played with the fomatting, but the Column subtotals doesn't achieve my goals.

Thank you for reading.
