Can you customize a tool's icon for personal saved tools?

Often when I’m working with ZBrush and getting into a groove I wish that the toolset I’ve been creating could be personalised with an icon of my own choice.

If I spend some time building up a set of brushes I wish to arrange them in a way that suites my personal approch and be able to identify them quicky amongst the existing tools.

This would speed up my work flow dramatically.
Oh to be able to script.

Any tips and work flow insights greatly appreciated ?
