I tried that and it didn't seem to work.

Dynamics take their other values from the general context For instance 
the varying "color" in the Dynamics uses the context gradient, the brush 
size is the context brush size, etc... And if I change a 
dynamics-related setting (fo instance, the "repeat") for one tool 
(brush), the value changes for other tools (airbrush, clone...).
