Toolbox Levels

I am creating a company-specific toolbox, for our networkusers, and I would like it to contain multiple levels; e.g.

Parts
Metric
USA
External Threads
Bolts
Studs
etc.

Hopefully, this conveys the concept of the toolbox structure I'dlike. This structure contains more than 3 levels - actually, I'dlike more than I've shown. However, SW Toolbox appears to belimited to 3 levels.

Does anyone know if SW Toolbox can handle more than 3 levels and,if so, how can I set them up?

Thanks,
