Is there a way to create a retrospective maintenance window to suppress/remove any alerts generated during the window?

swis.invoke( 'Orion.AlertSuppression', 'SuppressAlerts',uri,suppressFrom,suppressUntil)

Hi WSI, thanks for taking the time to respond. I have been testing with the API and have managed to get a historical alert suppression accepted but it doesn't remove any alerts that had already been raised for that node. The SolarWinds technical Sales guys believed it was possible to do by removing the relevant content from the SQL database but it's that process I'm having problems with. 

I would do the following:

Have each system with a custom property for maintenance start and maintenance end (as date/time type).

There are multiple benefits to this (in my opinion):

1. You can run a script to automate Muting Alerts.
2. If they pass you by, then you can use that timeframe to acknowledge/clear and add a note that this was anticipated downtime.

Just my thoughts given a few years with the platform.  I haven't been able to implement this myself, but the theory is sound.
