How to change a feature icon

Hi all
Does somebody know how I can change (by API) the icon of thefolderfeature?

I'm writing a macro that will had some component in anassembly,I've thinking of a macrofeature, but you can only addfunction in amacrofeature (not component). So I'll had mycomponents and I'llhad them to a folder but for a bettervisualization I'd like tochange the icon.
If someone can help or have some idea to help me.
I'm open to all the good idea you can have.
Thanks
