Create custom/ stop using New Account Template Notification

Summary:

I'm looking for the best approach to stop using the New Account Template (Security Console > User Categories > Notifications) for all.
Example is that HCM does not need this but Procurement does. We have explored using a different User Category for Procurement, but then we'd have to manually maintain the User Cat for these users. Another thought was to create a custom BI report to send these notifications just to our Procurement customers when they create a new account. Has anyone done this and possibly have an example? Or maybe a better way to solve this? Thanks in advance.
