Stepwise Regression with solution limited to max # independent vars - Best approach?

I am using MiniTab for stepwise regression. I have 25 independent variables I want to run through the stepwise procedure. However, I want the solution to contain a maximum of two independent variables. So I want the best two variables from the starting list of 25.

Is it possible to limit the solution to a max number of vars? If not, is the next best approach to simply select the most significant two variables from all the variables included in the solution?
