[Paraview] Question about Paraview and parallel processing

To whom it may concern,
I have some data which takes on different values in space, which
normally would be easy to view in Paraview. The problem is that the
space (which is a big cube) is decomposed into different subdomains
since the data was processed in parallel, and each subdomain is saved in
a different file. Currently, paraview interprets each subdomain as a
different time-step. Is it possible to get paraview to load all of the
parallelized data and view it as a single time step?
Of course, I could parse all of these files into one big file, but I
would like to avoid this extra step if necessary, since the files are
updated regularly, and an extra post-processing step would slow things
down significantly.
My files are in legacy VTK format. They look like this, for example
(the real runs are much larger than this):
#==== myData_00.vtk ====#
vtk myData
ASCII
DATASET STRUCTURED_GRID
DIMENSIONS 12 12 12
POINTS 1728 float
0.9519978E-01 0.9519978E-01 0.9519978E-01
0.2855993E+00 0.9519978E-01 0.9519978E-01
0.4759989E+00 0.9519978E-01 0.9519978E-01
......
#==== myData_01.vtk ====#
vtk myData
ASCII
DATASET STRUCTURED_GRID
DIMENSIONS 12 12 12
POINTS 1728 float
0.9519978E-01 0.9519978E-01 0.2189595E+01
0.2855993E+00 0.9519978E-01 0.2189595E+01
0.4759989E+00 0.9519978E-01 0.2189595E+01
......
and so on up to myData_07.vtk. Visit can stitch all of these domains
together with a simple file that tells what all the other files are:
#==== myData.visit ====#
!NBLOCKS 8
myData_00.vtk
myData_01.vtk
myData_02.vtk
myData_03.vtk
myData_04.vtk
myData_05.vtk
myData_06.vtk
myData_07.vtk
Is there anything I can do to get Paraview to interpret these as a
single data set? Any help would be much appreciated! (Also, my
apologies in advance if this is not the right place to post this kind of
thing.)
Best regards,
Adam
