I have 15 Exodus files that represent a heat conduction solution on 15 spheres at different locations in space. Each file contains identical sets of variables (though the variables have different values). I can load all 15 files at the same time, but is there a way to view a variable `temperature` in each file all at the same time?

When I click `temperature` in the drop-down menu, Paraview only displays the `temperature` variable in the last of these loaded files. Essentially, I want to avoid clicking on each of the 15 files and individually clicking on `temperature` in the drop-down visualization menu.

You could add all your readers to a `Group Datasets` filter. ![pqGroup](https://discourse.paraview.org/uploads/default/original/2X/e/e834d23b24e9389d1707302bcfb353f09f539ad0.svg)

That works great, thanks so much!
