Individual file open not possible of multiple file dataset

We cannot open an individual file of a multiple file dataset. For instance, (and this is true for any multiple file dataset), file open, then go to z_pinch1. If you click on the + sign, I see the following: z_pinch1.exo.8 z_pinch1.exo.8.0

What I expect to see is as follows: z_pinch1.exo.8 z_pinch1.exo.8.0 z_pinch1.exo.8.1 z_pinch1.exo.8.2 z_pinch1.exo.8.3 z_pinch1.exo.8.4 z_pinch1.exo.8.5 z_pinch1.exo.8.6 z_pinch1.exo.8.7

Found on git master, Linux, local server.

I am leaving this normal priority, but it would be really nice to have.
