Release PO after any change in PO

Dear Experts,

                     I have change the standard PO workflow WS20000075 to 3 levels and only using the RELEASESTEPCREATED. when user reject the PO in any level, "OTHER THAN 1st LEVEL" it reset the release strategy using BAPI_PO_RESET_RELEASE; after that PO becomes ready for approval again, as required.

My problem is that, when the 1st approver rejects the PO, it should be ready again for approvals after user do any change in the PO. Can I achieve this using RELEASESTEPCREATED event only.

Regards,

Sohail
