Compute mean,min,max,std up to each time step

Hi, Thanks a lot for the fantastic work you have done.
I have read through the documentation but I could not find an answer to my question which is"
Would it be possible to compute the mean, min, max, std of each column up to a time step (regularly up to each time step)

Currently what you do is that you convert the time series data into a single record by computing different features, whereas I was thinking to compute all of those features(min, max, std, etc..) in a times series manner and keep the data time series but we add additional features into the original dataset.
