Expense claim and PO batch approval

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

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

There are more than 20 expense claim approvals per day to our senior staff. Then there is almost the same number of transactions for PO approvals. The snowballing effect is daunting.

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.
