Feature request: Add tooltip option "Not completed by" for quests

Describe the feature request
There is an option for tooltip to show which character on the account has completed a quest.
Would it be possible to add an option to choose to show characters on the account that has not completed the quest?

It would be much easier to track a specific quest you want all your charcters to do to see who is left, rather then see who is missing in the completed list (having 30+ characters makes it abit hard to make out :) )
