Differentiate between Supplier registered Internally vs Externally on Supplier Spend Authorization Approvals

Content

Hello,

By default we are creating suppliers as Prospective supplier. Now at time of promotion to Spend Authorized we would like to follow different approval mechanism for supplier registered internally as compared to external supplier registration.

I was able to identify "Spend Authorization Request Source" attribute (with values as Manual Request/Registration External/Registration Internal/Registration - Sourcing Invitation/Self Service Procurement/Sourcing Award) which I think we can leverage to meet the requirement. 

Appreciate any thoughts/idea on how we can achieve the same or if we can use the above attribute.
