I have two xdmf file that points to different h5 files with the same geometry but different time steps.  
As an example, first xdmf files contains velocity infromation from t=0 to t=0.18 while the second xdmf file contains the velocity information from t=0.19 to t=0.48. Is there way to treat these two separate files as a single dataset in Paraview?

I can give these two xdmf files if it is necessary.

Best,
