Basketball-Reference "snapshots"

[ISHGoat]

There are always updated stats/metrics. For example, GSW is currently 4-0 with a 25.0 point differential. Is there a way I can view data on a particular date in the past? For example, I want to see GSW's point differential, SRS, SOS, and other advanced metrics in the 2014-2015 season as of/up to March 31st, 2015. Is something like this available?

look at the game scores and add up the differential

look at the first four game scores and add up the differential

I just gave a very simple example. I could obviously build my own advanced stats like SRS, SOS, point differential, etc, but I was wondering whether there was existing tools that allow me to "look into the past"
