[Paraview] Howto read files with a numerical extension that are not a timeseries?

[RVA Developer]

Hi,

We have data files generated by UTChem that are numerically ordered
that we read with our own custom Paraview reader-
mymodel.HIST01
mymodel.HIST02

However these "HIST" files correspond to different objects (vtkTable
data) NOT timeseries data.
When we rename one of them to just "HIST" our custom reader can import
the file. We now need a more robust solution.

How do we override Paraview's TimeSeries proxy so that we can select
one or more of these files and read them in as separate vtk objects?

Note, we are building our own Paraview so we could patch Paraview code
if we have to but we'd rather not!
Some advice on where to start would be appreciated (e.g. similar file
readers or Paraview classes that we need to extend/modify).

Thanks,

Nemo.
