Do not split the final week of the year into "week 53" and "week 0" in Data Warehouse

When using data warehouse, asking for week granularity in year end, it automatically splits the last week in "week 53" and "week 0". Therefore making it impossible to have unduplicated visitors or returning visitors or any other metric for that specific week. It would be nice if, with week granularity, we could really have it. Not getting data for two split weeks.

Thank you for this.
