Can we save custom brush settings?

[Ritergeek]

I'm working on a complex project that involves using a long list of brush settings for different sections. Since I'm keeping parts separated into thirty some layers and counting, I've resorted to entering relevant brush settings in a text document so I can redo sections or replicate. Is there a way to create a palette of brush settings within a GIMP file? It's tedious and time consuming to redo opacity, size, hardness and sometimes spacing each time I switch layers!
