Hello experts.  
I am trying to load a state file using paraview.simple, version 5.10.1.  
I am using LoadState in paraview.simple to load a state file.  
Is there any way to visualize a sequentially numbered file using a state file?

For example,

```auto
for dnum in range(100, 200 + 1, 10):
    file_path = “FULLPATH/data-{}.cgns”.format(dnum)
    LoadState('a.pvsm',
              LoadStateDataFileOptions='Choose File Names',
              DataDirectory='FILE DIRECTORY',
              filenames=[file_path]
            )

    output_filename = output_filename.format(dnum)
    SaveScreenshot(output_filename, GetActiveView())
    Delete(GetRenderView())

```

and I tried this, but only the data-10.cgns in a.pvsm is loaded.  
Is there a built-in search/replace mechanism I can use to make this work?  
Thank you!
