In one of my project i have a multi-select custom field. I would like to filter all task that don’t contain specified selections from my custom field. Is it possible to add such feature?

That currently works via the project filters.
Under “filters” within a project click “Add filter”
Then scroll down to locate the relevant multi-select custom field and you have the ability to pick which options should show and which not.
