Why Default SFDC integrations are not available for newly created standard commerce process?

Summary:

Hi Team,

I have created new standard commerce process(customcommerceprocess1). When i tried to navigate to integrations of that particular commerce process(customcommerceprocess1), I can't find any default integrations (Opportunity Import, User Import..etc) but i can see those integration on default commerce process (oraclecpqo). My CPQ site is already connected with my salesforce instance, and it was provisioned with Salesforce Ref App. In this case, it should have default integration for SFDC (For including newly created standard commerce process). Why default SFDC integrations are not available for custom standard process?
