Need a way to determine the length of time a user has spent on Aha Merged

In order to gage adoption and uptake of Aha, as an admin we need a way to not only see when the last time someone logged into Aha, but it would be helpful to see the total time spent on site. This way we can provide additional guidance and support to those that may be resisting using the tool. An extra column on the user export would be a great place for it
