Allow merchant to convert a regular shopify product into an experience in the Experiences app

As a merchant, I want to be able to link an existing Shopify product to an experience and/or turn an existing Shopify product into an experience. Also, I may have an integration with a third-party ERP (e.g. Netsuite) that requires the product to be created in the ERP first and then synced to Shopify. Since the Experiences app currently requires that each new experience is first created in Experiences, which is then created as a Shopify product, it isn't possible to "add" Experiences to an existing Shopify SKU or work with ERP integrations that must be the "source of truth"
