Allow option to exclude in Advanced Filter

It would be useful in some cases to be able to filter out segments. Some options exist of course, such as 'Exclude number only' and 'Unlocked' (= exclude 'locked'), but in some cases it would be handy to have an Exclude option at the top of the Advanced Filter instead.

For example, we can use the Advanced filter to see either only first occurrences of repetitions or all repetitions excluding first occurrences. It would be nice to be able to set this filter to 'Exclude', for example to show all segments except repetitions excluding first occurrences.

Or if you wish to exclude segments based on document structure elements, instead of having to include all the other elements.
