I would like to see the ability to change a timeline end date upon a status change.
If a project is completed prior to the end of the expected timeline then you should be able to adjust the status to “done” and the timeline can update automatically.
Welcome to the community! It is possible to set a date to today when a status changes. With the app “Start + End = Timeline” two dates (start and end) can be sync to a timeline. When combining these two in one automation you can achieve what you want.
