Is it possible to add such an option for multiple-selection filters ?
This would save a lot of time when excluding specific values : we would be able to “select all” at once, and then untick unwanted values.
The workaround that consists in having an advanced filter, and select “is not” before entering excluded values is not super confortable. “Select all” would definitely improve user experience
Same as what excel / google sheets provides when filtering on columns :
