I need a new filter option on the drop down options, we currently have 'is one of' which is great to show multiple vendors as I am using the vendor view field here. But there is only 'is not' available to exclude a vendor, I need to exclude multiple vendors, the way I can view multiple vendors with 'is one of' therefore can you please create an option 'is not one of' this can then list all of the vendors that are not required for viewing.
