If an admin is in the Report Suites > Edit Settings > General >
Calculated Metrics > Under Manage, if X (delete) is selected, a warning
should appear that says something like - any reports and/or dashboards
that are using this metric will be affected, are you sure you want to
delete? -- Currently, if an admin selects the X there is no way of
recalling the deletion. We had a number of dashboards that were affected
by this removal.
