Dynamic setting of the PrintMode-parameter in smartForms

This is a real challenge for experts!!

Is it possible to change the parameter 'PrintMode' of a smartForm dynamically while (or just before) executing the corresponding FunctionModule? Some users like the printform in SIMPLEX mode, while others prefer the same printform in DUPLEX mode.

I'm not really interrested in copying the smartForm - one with SIMPLEX and the other in DUPLEX mode ;-(

Thanks a lot for your help.
