Save custom brushes without default brushes

I have created a library of brushes that I want to save to a blender file, so that, at any stage, If I want to use them again, I can append the file, select brushes, and they will all be added to my library.
The problem is, that all the default brushes are saved as well, so if I want to append them, I then need to select each one individually using ctrl click, which is a pain. How do I save a library of brushes, without the defaults?

Edit* I found Blender Brush Manager, and that seems to do the trick
