Redwood Processing Requisitions with 6 or more lines

When in Redwood Process Requisitions (New) Pages, processing requisitions with 6 or more lines: After you have published the staged requisition(/s) it creates a draft Purchase Order. There are two ways to edit and submit the draft Purchase Order to make it Open and sent to the supplier.

1. In Redwood Process Requisitions (New) Clicking the all lines tab, finding your PO, clicking on the PO's hyperlink, clicking edit and then clicking submit.
2. Navigating to Redwood Purchase Orders (New) finding your PO, clicking on the PO's hyperlink, clicking edit and then clicking submit.

These both bring you out to the Redwood Purchase Orders (New) page, where there are no links back to Process Requisitions. Can I ask why it behaves like this; why Processing a Requisition to create a Purchase Order is not all under Redwood Process Requisitions (New) page and it brings you out to Redwood Purchase Orders with no link back to Redwood Process Requisitions.
