Transfer authorisation while maintaining substitute

[Sangvir Singh]

Hi All,
I have a requirement for maintaining substitutes in PO approval workflow.
Sceanario is:
If approver is on leave, substitute should approve the PO, however, substitute do not have authorisation to approve it.
Is there any way through which we can transfer role to approve PO when substitution is made active.
Can we make use of any BADI or exit here? Kindly note we have to approve from SAP inbox and not UWL.

Any pointers on  this would be helpful.
Regards,
Sangvir Singh
