I’m using an Alarm Status Table filter to show only alarms from certain machines. I’m using the syntax of \*_MM02_\* to show only those alarms where display path contains our machine 2 descriptor. On our alarm page for machine 1, I’d like to show the alarms with MM01, but I also want to show alarms that are not specific to either machine. I’d like to show NOT(MM02). I’ve tried !MM02, !MM02!,![MM02]. Is there a way to exclude items in this filter?

You'll likely have to do this via scripting. Look at the extension section of the documentation. You'll basically do if the name is MM02 then return false otherwise true.
