Needed: Quota Details History

[thstart]

We have a Billing History, we have now 

Estimated Charges Under New Pricing.

We need also Quota Details History.

Estimated Charges Under New Pricing shows "Used" be I would like to have 

the ability to go back and check the actual usage as it is now under 

Quota Details.

This can help optimization, also will prevent questions I see now in the forum:

"actual usage is different than reported".

Best,
