Need Unit Number - Closed Purchase Orders Need Sorting by Date

Today I needed to view a closed purchase order and found the new system could use some additional work. The purchase orders do not show a unit and as an Admin for five units, all PO’s are intermixed, not unit number is shown, and they are not in date order making it really difficult to find the one you need. Adding the unit number to each PO would be a great step forward as would having the PO’s listed in date closed order. Thank you!
