If both displays are in the same view or two views with the same projection,
you can use the Edit->Sharing->Sharing On in each of the cross sections
to share the cross section position.  For  data probes, you can have one data
probe with multiple parameter so the position is shared.

Alternatively, you should be able to use the simpleDifference formula to 
quantitatively calculate differences and this could be used in the data probe
as well.

I'm not sure I'm understanding what you want here.  I'm not sure how this
solves your problem.

BTW, I recently added a "Miscellaneous->Make a time sequence from single time 
grids/images" formula which takes single timestep images or grids and merges 
them into one sequence.  However, this requires that the times be different 
for each image. Not sure if that helps.
