Retaining fill-in data adjacent to pivot table

I have a pivot table that extracts data that meets a certain criteria. When the data is extracted, it needs to be 'signed off' in a cell adjacent to the row that contains that data using a drop-down for the person's name and the date of the sign-off.

However, if the original data changes, the extracted data may now appear in a different row, but the signed-off name and data cells stay in their original row and now don't match up to the exracted data.

Is there any way to ensure that the extracted pivot table data and the signed-off cells always stay in the same row?

Thanks!
