Allow for custom workweeks

Description

Allow the user to set their own workdays and this to be used for timelines, example is that I’m currently working on a project with 4 workdays a week, it becomes incredibly difficult to work with timelines and gantt charts in this case as dates will have to be set manually.

What are you trying to achieve

With custom workweeks you’d be able to have timelines and Gantt charts line up with the actual project timeline
