Is it possible make filter that deletes events older than for example five days?

I do mocord with four cameras daytime, and record one camera (other disabled) at night (motion detection does not work correctly at night)

I want to delete recorded events for this camera that are older than 5 days, so that they don’t fill my disk.

I know there is purgewhenfull filter, but this way I know that I have five days allways left. And it would not delete other camera events.
