For working on time series is it possible t define operations on x which work intra column?

[sam34567]

I am working on time series data and would like to use moving averages, step differences etc as operations. I know I can always compute such quantities on raw features but if I can define them as operations they could be stacked on top of other operations like for example diff5(ma10((x2-x3)/x4))/ma10(x2).

Let me know if these help?
