Summary Archive Content by Date (monthly) Report

Hi

Given a specified archive I'm looking for a way to summarise the content (item count and size) by month, something like the below would be ideal:

Month    Count    Size
2015-06    100    10
2015-05    125    12
2015-04    150    15
...    ...    ..

I have related queries (https://www-secure.symantec.com/connect/forums/archive-folder-and-item-counts& https://www-secure.symantec.com/connect/forums/summarize-archived-data) but can't figure out a way to filter the savesets by archive.

Any help would be greatly appreciated.

Thanks
