+1 for this feature! What I need is pretty similar: calculate rolling sum, so for each day, I need to sum the previous 30 days (on each point). Oracle and Postgre make this very easy with aggregation function (and they can take advantage of very interesting optimization for sum, as each point is actually the sum of previous day + sum of elements in the given day). Actually, the simplest way I've found is asking for more data (so if I want rolling sum for 30 days, I ask for 60 days, and do the sum myself). But this is quite inefficient.
