How required link from Purchase Requisition to RFQ to Purchase Order?

I understand that three (3) Modules below are can be created individually.

1. Purchase Requisition

2. RFQ / Quotation

3. Purchase Order

I want to know if its possible this scenario with same Document Type like (FIXED ASSETS), that can be linked from PR to RFQ to PO? (All Released)

1. Create a RFQ transaction which is REQUIRED to have a release PR transaction?

2. Create a PO transaction which is REQUIRED to have a release RFQ transaction?

If so, how it will be done?

Please need you advice.
