Multiple Microsoft Graph Collections?

Hello, I already have the postman collection for Microsoft Graph forked and working (Postman)
All of the requests are working as intended, but I’m noticing that even though there’s quite a bit, there isn’t much in terms of Security requests. For instance, I want to bulk dismiss Risk Users. So at first I just thought Microsoft didn’t have a request for that. But then I found this - riskyUser: dismiss - Microsoft Graph v1.0 | Microsoft Learn
So I made a custom request with it, and it worked in Postman. So the official postman collection for microsoft graph seems to have about 1% of what is really possible in Graph.

I guess what I think my question is… how can I get everything in here (Microsoft Graph REST API v1.0 endpoint reference - Microsoft Graph v1.0 | Microsoft Learn) into Postman?
Thank you!
