Detailed Date Ranges

Hi,
I was wondering if it was possible to get behaviour as
http://demo.piwik.org/?module=API&method=VisitsSummary.getVisits&idSite=3&period=day&date=last10&format=xml

but with a custom date range instead of a something like “last10”.

I need to be able to specifiy something like
http://demo.piwik.org/?module=API&method=VisitsSummary.getVisits&idSite=3&period=day&date=2012-11-01,2012-11-21&format=xml

If I use period=range in the above request, it only gives me the total during that range.

I want to avoid having to use something like “lastX” (where X is big enough) and then simply ignoring the values that are too recent because that would be hugely wasteful on resources for an old date range.

Note that this isn’t for charting or anything, I just want to get the raw data from the API for the appropriate range.

Specify the comma separated list of dates you wish to request in &date=
