Recently you can only save the drill-down (subreport) information manually. We will think how to make it possible in the next versions though.
There is also Alarms Current State Overview report showing all currently unresolved alarms. There is no subreports in it.

You can include users` objects in Business View groups and choose them in the scope, so the report will contain errors of only one/chosen users.
The report can be scheduled to generate automatically.
Hope that helps. Thanks!
