Pronterface Macro variable

Hey Forum,

Im trying to set up a custom button to control the speed of feeding the material in pronterface.

By f.e. M221 S120 i can overrride the extrude factor to 120%.

Is there a way to use a variable instead of S120, so that i can type in the factor and then hit the button or something alike.

Otherwise i need a button for every percent

Thanks,
floe
