Not logged-in user records

There is a choice to filter records connected to the logged-in user. I'd like to have a filter to select records NOT connected to the logged-in user. For example, I have a table that allows a manager to review submitted records for approval. I'd like to be able to select all records besides the logged-in user so they can't approve their own records.

I've opened a ticket about this during the beta program of the new builder and am commenting here on request of Knack Support as well. 

I hope more people follow & comment here as this option can open up a whole new area of business for us. 

anyone managed a workaround to filter records not connected to logged in user ?? 

Is there an in-built variable to refer to the logged-in user?
