Supplier Request For Quotation & Opportunities

Is there a way to add supplier request for quotation as a related document to opportunities. Supplier Quotation and Quotation already are, but not the request.

I have the ability to program/implement this myself if need be. Just need to be pointed in the right direction.

Perhaps you can use dynamic link fields. Refer the link below
