How to view variable in multiple files concurrently?

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

That works great, thanks so much!
