Limit BAQ Rows Returned

Is there a way to limit the number of rows returned by a BAQ?  I have a zone BAQ that I attached to my PO which shows the part transaction history for that part. Mainly the Last date it was purchased, the PO it was bought on and the amount we paid. I limited it by date, but I would really prefer to limit to the last 5 times it was purchased.

Any thoughts.
