In CRM, I want to show charts which are grouped by week. This is nice and easy (albeit irritating that you have to show week numbers rather than getting the choice of showing week commencing/week ending dates, but that's not important now).... the difficulty is that I only want to show the last 13 full weeks of data. The only way I can find to limit the data is Age in Days. As a result, the first data point on my graph is part of a week 84-91 days ago.
I would love to see the options Age in Weeks and Age in Months (or similar) in order to give a true rolling week-by-week/month-by-month comparison over time.
If there is a way to do this that I'm missing, please let me know.

Moderation Update (February 2026):
From the time the post was originally made, extensive date filter criteria (that also solve the case discussed) have been supported in CRM Reports. Therefore, we are locking this post.
