Add a column to a pivot table

Hi all,
Currently, I have two reports in a dashboard like this:

The OH quantity does not have any date reference. Would it be possible to combine the two tables by adding an OH Quantity column to the incoming supply? So when I filter by subcategory, I can see OH Quantity and the incoming PO Quantity on the same table?

Thank you.
