Query while applying approval on Invoice Hold

Please guide us on the below queries while applying hold approval on the invoices:

I have configured the AP invoice hold approval workflow and it works like when we apply manual hold on the invoice, it triggers approval workflow and approver has two options either he acknowledge or can release the hold, whatever task he do it completes the approval workflow. Please confirm, is there an option that whenever, Ivoice hold is released manually by the AP user and FYI notification can be sent to the Invoice hold approver?
