[Paraview] Comparing datasets - taking a difference

[Christof König Beatty]

I have a follow up question to one I asked a while ago.

While I manage to take differences between two sets, my method (outlined 
below) only allows me to do this for one time step at the time.

Is there a way to take a difference for all times at the same time so 
that I can look at those differences over time, save it etc.?

Thanks!

Chris
