Organization With Different Definitions of "Week"

Hi!

I work for a large organization that operates in many different countries. Some markets define "week" as Mon - Sun while others define it as Sun - Sat. What is the best way to set up/organize my report suites to account for both of these week definitions for each market? 

For example, our UK report suite is set up to define weeks as Mon - Sun by default. However, I am in the US and would like to have the ability to view weekly UK data using Sun - Sat weeks. 

Would multiple virtual report suites for each country be a possible solution?

Thanks!
