Disable alerting for a group/datasource combination

We had an issue where an aspect of a service on a group of systems was intentionally shut down for a while. This, of course, generated lots of alerts. Since the thing we shut down was going to be down for a while, we decided it would be good to just disable alerting on that datasource for that group only.

There doesn't appear to be a single-click way to disable all alerts from a datasource only for a particular group. The only way to do it is to disable all the data points within the datasource for the group. Which usually is ok -- in this case there are literally hundreds of data points. Not a convenient disable.

Can we get a single-click group/datasource alert disable feature?
