Blackout at system/account level instead of monitor level

Hi.  New feature suggestion regarding blackouts... We have maintenance days scheduled throughout the year where we create a blackout using the bulk settings for all monitors.  Even though we know the schedule for the entire year in advance, we cannot setup the blackouts in advance for the entire year because the blackouts are done at the monitor level.  Meaning if I wanted to setup a blackout for an event three months from now, I can only select the monitors that exist at the time I'm entering the blackout.  If any new monitors are created between the time the blackout was entered and when it actually takes place, they would not be included.  Having a way to blackout at the account/system level that would include anything not yet created would be helpful.
