PO batch approval

I would like to raise the topic on "batch approval" of Oracle Fusion procurement.

We’ve been running Oracle for a year and now actively using Oracle I would like to explore batch approval possibility to Purchase Order as the volume is becoming an issue.

There are more than 20 PO approvals per day to our senior staff.

Perhaps there could be system processes and administrative procedures together that could help to alleviate the tedious process, especially for low value and regular transactions. Is there a way that our approver could perform "batch approval" instead of approving one by one? Imagine there are some POs with small amount but reaching approvers by rule.
