R12: Supplier Approvals - Internal creation & update

Hi

I know with AME and iSupplier we can route prospective suppliers to an approval routing.

However - for

a) internally created suppliers

b) supplier updates performed by AP / PO team directly

I cannot see anything here to manage this beyond access controls?

Without SLM is there any way to have an intake for supplier update requests and route them appropriately?

Even for supplier generated requests they appear to go to all users with access to the form, with no ability to use AME or similar to track and manage the update requests.

Curious to see how others have approached this, the alternative of managing intake requests for new/updates on an offline system (eg sharepoint / other) just isn't appealing and the team are keen to use a single centralised system for all supplier management related tasks.
