Photoshop Brushes Help???

I just downloaded some new photoshop brushes,

And most of the sets of brushes I got came in one .abr file.

But there was one set in particular

Where each brush came as a separate .abr file.

Is there a way I can merge all of the separate brushes into one abr. file so it does not take up so much space?
