How do I associate particular brushes with a project?

Hi everyone. I like to experiment with different brushes when creating new projects so that my art has a varied style. Is there a way to associate particular brushes with a particular file?

For example, if I'm working on an illustration of a dog I might use one brush for the line and another for the fill. Then, when I move to a new project, e.g. a painting of a building, I might want a different brush for the line and a different brush for the fill.

My solution has been to take screenshots of the brush panel or make a Notepad file but surely there's a better way to organize brushes? Oh, and I'm switching between Photoshop on the iPad and on a Window PC.
