XF 2.2 See & Monitor user storage sizes

[PapaTango]

I have searched and likely missed something, but I cannot find anything that will enable me to see how much a user has uploaded through their account--as in TOTAL amount (in MB/GB) for attachments and XFMG albums? I recall that this feature was standard in Invision ACP, but is startlingly missing in XF?

Any suggestions? I have to find a method to find these individual account holder metrics.
