We're able to Query RE NXT Alerts and RE NXT Summary Notes. However,  these fields do not yet exist as options under Admin / Import.

We depend heavily on Alerts in particular. The ability to display alerts was one of the major NXT selling points for us. However, we were also accustomed to being able to import Alerts. It's something we did often (daily or weekly). The ability to import Alerts and Summary Notes is something we would use often.
