Hi network - I am wondering if it is an option in Planner to mirror lines in the Gannt chart. If e.g. you want to extract the most relevant tasks from an extensive schedule and highlight them in the top of the schedule, but at the same time not have to update them more than one place, namely down among all the other less significant tasks.
@Jesper1508 Planner doesn't have a Gannt chart - are you thinking of Project for the web or Project Online? The timeline feature in Project Online - or maybe the Roadmap feature for Project for the web might meet your needs.
