st: regress and then extrapolate with new dependent vars but same coefficients |

Hello,
I need to run an exercise in which after running a regression and predicting
the y_hat, I need to replace one of the dependent variables with zeros and
then use the saved coefficients to predict a hypothetical value for
y_hat(given x1==0), in order to compare the predicted values from these two
exercises.
Does any one know how to do this quickly, without saving all the
coefficients and manually predicting for the second step? I am running a
regression with 174 dependent variables (mostly dummies) and it would take
some time to predict manually.
I've checked on the faq for this and was unable to find anything, i might
have overlooked the answer and apologize in advance if it has been asked and
answered already and would appreciate any references if so.
Thank you,
