Trigger qualification when supplier contact is created

Summary

How to configure rule set to be based on creation of a new supplier contact, rather than new supplier

I have a use case where my client imports suppliers (in spend authorized status) from credit safe. They then manually create a supplier contact who is designated as the qualification contact person (custom DFF checkbox on supplier contact). 

We're currently on Fusion On-Prem (R12) and have a custom process which will create an initiative for the combination of new suppliers and contact, meaning users do not have to manually create the initiative.  We are looking to upgrade to Cloud (R13) but the business requirement remains the same i.e. create an initiative for when the we have a combination of new supplier AND new contact.
