Mass acknowledgment of PO's from Supplier Portal

Currently, we want our suppliers to acknowledge POs through the Supplier Portal. However, suppliers need to use the ADFDI option to mass acknowledge the POs. We wanted to check if there is any way to acknowledge multiple POs at once without using the ADFDI option. Also, even when using ADFDI, it is only pulling newly created POs and not the POs that were changed or canceled. Because of this, users are forced to manually acknowledge the changed or canceled POs individually. Is there a way to mass acknowledge all PO types, including newly created, changed, and canceled POs?
