Filter Request: "Is NOT in the last"

It would be REALLY nice to have some filters for:

Is NOT in the last (for example, give me results where STATUS is NOT in the last 30 days).

One use case is to highlight projects that are older than 30/60/90 days in a dashboard. This would also work well for billing and other items, and it seems like an easy add to flip the value on the “is in the last” filter.
