Suggestion: filtering collection on "not in list"

I have many lists… For each model car brand, but also for each country/police force. So, most of my models are (supposed to be) in 2 lists. Now I want to ensure that - for instance - all my GreenLight models in fact are included in my “GreenLight” list.

I enter “GreenLight” in the Any Keywords filter, so that gives me all my GreenLight models:

In the Organization section of the Filters, there is the “IN ANY LIST” filter, where I can choose a List, which will show me all items in that list:

But I am looking for the opposite: I want to see all my GreenLight models, which are NOT in that list… Is there any way, using the existing filtering options, to get me what I want?

If not , can something be created?

Would anybody else find such feature helpful?

Search for Greenlight and then look in the column List to see if all of them are in the right list. We should be able to sort that column, I will add that to the Queue.

Please let me know if that works.
