Feature Requests: Starting the week on Monday

This may have been covered before, so I appoligise if thats the case. I would like to know if there's a way to start my week on a Monday, my training program starts on Mon and finishes Sunday with my long run, with the current calander when I do a weekly report my Sun long run is in the following week, not the week of my schedule, a minor thing but is there an easy way to overcome this.

Regards Mick
