Hello,

I am using the `Plot Data Over Time` filter in Paraview to post-process an OpenFOAM case with many fields and time steps. The problem is that it takes a very long time. I have seen [this thread](https://discourse.paraview.org/t/how-to-increase-the-performance-of-the-plotdataovertime-filter/3022). But I think it is not related to what I am asking here.

Is there a way to select only some specific fields **before** running that filter? so one doesn’t wait until the filter finishes than unselect the fields he doesn’t need to be plotted?

So ideally, the filter should ask you first what fields to plot (allowing to unselect the uneeded fields) then plots those fields.

Thank you
