How to invoke Manage approvals on clicking submit in requisition creation

Summary:

We have a requirement to check if the approvals are generated or not, on clicking 'Submit' button in Requisition creation screen, as the requestors might not deliberately click 'Manage Approvals' every time before submitting the requisition.

This is similar to the functionality that on clicking submit, system does a funds check internally even though 'Check Funds' is not clicked explicitly.

On the same lines, we wanted to understand if there is any configuration/setup which can internally invoke Manage approvals on clicking submit in requisition creation. so that requestor knows if the approvals are generated or not, on clicking submit.
