Add 'Assigned date' to user roles
We often need to know the date that a role was first added to a user's account. The status date is not static and because we use the API for updates from our SIS the status date often gets updated with random dates. The API updates also make the history tab difficult to use to track down role additions versus changes.
We should be able to easily see a column that includes the date a role was initially assigned/added in the context of all of their roles in the General Information tab.
We also need the date a role was added to be available in Analytics. We need the ability to generate reports that include this information as part of our user management strategies and to identify and troubleshoot potential widespread issues where checking user accounts individually is unsustainable.
