How do you exclude an entire taxonomy

Hi,

I understand how to do exclusions, but what if you want to exclude something from all of a specific taxonomy.

For instance, I want to exclude an ad from ALL event-categories, but when I go to do an exception, I cannot find any value to just exclude that — it appears as if I need to exclude each and every member of that taxonomy individually.

There must be a way that I’m not seeing.

Thanks
