[R] Poisson regression with GEE using stepwise selection of independent variables.

Is there any way to perform stepwise Poisson regression with GEE in R?
(I know, and agree that stepwise procedures are not best statistical practice. I have developed a model with 10 independent variables, my client want me to include 50 other independent variables. I, of course, don't what to do this. I am hoping that I can demonstrate that adding additional variables does not make a material change to the results, but I don't want to have to perform this arduous task by hand).
Thank you,
