Hide weekends from workload view

Is it possible to exclude / hide weekends from workload view?

I use to drag&drop single tasks in the workload view and the problem is that if I move a task from a Monday-Friday period to over the weekend e.g. Thursday-Tuesday then I need manually to extend the bar of this single task to avoid the over-load situation (red colour). If there would not be shown weekends at all then I shouldn’t adjust the bar width at all.
