Getting matrix transform delta of Niagara system

I would like to retrieve the delta of the transform of the parent component in my Niagara system. This would then allow me to re-position particles as well as calculate accurate velocities. Currently I can get transforms from Engine.Owner.SystemLocalToWorld (among other matrices) but I would like to get the difference in transform matrix per frame; the delta. I have tried to store the matrix of the previous frame and read it back, but this does not really seem to work. Maybe anyone could advise me on some approach to this?

Thanks in advance!
