How to set a field to retrigger the Approval Process during Edit Requisition?

Hi -

Need help on how can i set a field in Edit Requisition - Review and Submit page to retrigger approval process once i edit its value.

Note that it is not a change request process.

Step:

Create a requisition

Submit the requisition

On the approval page click on the edit requisition

Then edit this specific field and submit the requisition ( I want to set that everytime this field was edited reapproval process will be retrigger once i click the submit button)

Appreciate if someone can help me.
