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?
