This is similar to [summing cell values in region](https://discourse.paraview.org/t/summing-cell-values-in-region/4201) where I would like to do a number of operations on different RegionId’s at each time step (ex. integrate cell data) and store it in a table or whatever type is best. Is there a better way to do this rather than manually changing regionID threshold?

Thanks!  
Zak
