We frequently encounter duplicate entries in custom fields for emails and titles during task creation, leading to data redundancy and inefficiency.

That is why I propose implementing real-time duplicate validation with notifications for custom fields during task creation and updating. This feature would alert users about potential duplicates instantly, allowing for immediate correction.

It could be nice if it was a option where you enable a toggle in custom field settings to activate real-time duplicate checks in that list. Notifications should be visual and textual, alerting users directly in the task interface.

This feature would streamline data management and improve operational efficiency by preventing duplicates at the point of entry.
