Custom periods of time in precipitation accumulation

Hello! Love your website!
I am missing only one feature: to be able to set custom periods of time in precipitation accumulation. It would be great to set exact time in the forecast, not only granted by default for some starting point in the past. For example, to set accumulation from tomorrow midnight and then use the time scale. Or whatever hour I would like. That would be great!

Thanks for the idea. It would certainly be a nice feature, but it's too troublesome to create. We need to pre-generate the data, and we cannot have so many intervals pre-generated.
