Making Unsupported events supported...

Sentinel 6, latest patches:

So started using Identity Managers, do-generate-event token, and I made
up an Event # of 1007 - 1020

We enable show Unsupported events on the channel and we start getting
the events. yay! But they come in as Unsupported Events.

Well from our perspective, these are now supported.

How do we change this? We are trying to edit the taxonomy file to
change it... But running into all sorts of issues.

Is there a good summary? What are the files that specifically need to
be edited and what are the values we can set/use?
