Last XX Events filter

I have some IPSEC VPN objects on some Nortel Contivity branch office devices.

The tunnels go down when there is no interesting traffic traversing them, and when they come back up they always have a new interface index, which orion picks up gracefully (I'm impressed!)

 However, the problem here is that it's really filling my "last XX Events" full of garbage events I don't care about.

I need to find a way to exclude items from the Last 25, 50, or XX Events interface with a filter.

Is there any way to do this?
