Average values of tier buckets

When using tiers, it can be deceiving when looking at cohorts within tiers comparatively in the event the buckets are different sizes.

For example if I’m trying to show days since last purchase in buckets, the number of shoppers in each tier are relative, but the number of shoppers per day in the bucket can normalize and tell a different story. For example, 0-7 days since last purchase, 8-30 days, 31-90 days, 90-365 days and over 365 days.

Is there any feature I’m unaware of that would normalize those buckets to show how many users fall in each bucket, normalized for the number of days within the tier?
