Hi, I am wondering if there are any workaround on creating a lag transform to do RollingSum. What I can think of is Multiplying RollingMean with a constant values. But the Combine method only allows usage of

_BaseLagTransform

. Maybe also if there are any ideas on RollingCount. Do anyone have any ideas or experienced with something similar? Thank you!

Okay, I will look into it, Thank you!
