Increase segments in Bezier through macros

Hi,

I am in a postion where I want a closed bezier to be converted to a closed polyline without changing the shape to the maximum extent, because some of our clients don what bezier curves used in thier drawings. What I want is as a begining, to divide the whole bezier into small parts where the number of segments increase to a maximum, so that the overall shape is almost the same. I can do it manually using 'Shift + 5'. But there is no point in doing it manually.

Is there a posiblity to add segment points in between using macros ?

Please give your suggestions

Thank you
