The ability to adjust the suggested reorder levels on Purchase Orders

The ability to be able to select which "sold in last" period you want to auto assign to PO's.

For example in the run up to busy periods, the ability to default to 60 or 120 days worth of sold items to the PO instead of 30 days in the suggested order qty column.

Even better, the ability to be able to choose a date period and have sales from that sales period assign to the suggested qty so you can see what sold in the same period last year for example and reorder that qty.
