How to set the path for individual BuildServer data folders.

In an effort to improve our server performance I would like to split a few of the data folders onto seperate drives as recommended in the following document.

I have been able to relocate the primary folder which includes messages, artifacts etc to another drive but would like to subdivide this further. Does anyone know where/how do you modify the location for an individual folder?
