Very often a task is not worked on continuously. E.g. I might plan to work on a task Monday, next Wednesday, half a day the week after, and then 3 days consecutively.

I would like to be able to plan a task in this way, and then it should also be visualised as such in Gantt, Timeline, Calendar etc.

It would also allow to plan holiday with one task per resource rather than a task for each holiday period of a resource.
