I would like to be able to exclude multiple messages at once in Syslog viewer. Right now, you can exclude a single message by typing !%message% in the Message Pattern field, but there is no functionality to exclude multiple messages at once. For example, say I would like to filter out all the messages that read: Deny icmp src Outside,
As well as: No matching connection for ICMP error message
It would be nice if I could do this by typing something like !%Deny icmp%, !%No matching%
Or just !%Deny icmp%!%No matching%
Trying to avoid setting up and using Filter Rules, as I don't want to have to remember to turn them on/off.
