Linking Supplier RFQ to Opportunity created

Hi all, I would like to be able to create a supplier request for Quotation after creating an Opportunity. After Saving the opportunity only the Supplier Quotation and Quotation options are currently available. Is it possible to create another plus sign for RFQ? I would like this to be on this form so that I can convert this to RFQ and send to suppliers if need be. Please advise and see picture of what I am referring to.
