Reports Grouping By Week

We have set our Global Company Calendar to have it's weeks start on Saturday. However when we design reports which group by week the report does not respect that setting and the groupings of data are using a Sunday week start pattern. I was instructed to submit this as a feature request.

I am requesting the ability to select within a reports design or within the settings the ability to tell the reporting module to respect the Global Company Calendar setting "Work Week Week starts on:" when grouping data by week.

Thank you.
