Counting up CCAction?

Is there an easy way to do a counting up animation? Like for example, I have a CCLabelTTF that has something like “Gold x000” then it would count up for 2 seconds until it becomes “Gold x100”

I could do it using schedule* but is there a much easier way? Something like aCCCountUp::create( float duration, CCString * format, int value )* where duration would be the time, format would be the label’s new string (like “Gold x%d”), and value would be the variable we want to manipulate in that 2 second period.
