Hey Steve
I don't know of any inbuilt way to do this. It's possible (if you are on SaaS or have the connector for On-Prem) that there is something in Intelligence that could give you that information.
If not, then you could do an API call that will get you that information (enrolment date can be used for number 2), or if you have On-Prem you could query the SQL tables directly.
If you work this out, I would be interested to see it as I'm sure at some point ill be asked to create something similar.
