Of course, there is and you mentioned it yourself: a preset. When you have your Brush, and have all the settings the way you want, you just save everything as a preset and it will be available next time you want to do the same thing on a different project. What it does not have is a way to save ONLY what is inside the Brush Variance palette. That makes sense because the same window will appear if you are using the Brush tool, the Eraser tool, even the Clone tool, but some settings will not be pertinent. For example, the Color Blend is greyed out when you use the Eraser tool the Saturation is greyed out if you are using the Lighten/Darken tool, etc.
