Is it possible to have two separate model blocks in a dynare .mod file?

Specifically, I have some equations that are non-linear and some that are linearized. I want to include the non-linear equations in one model block and have dynare log-linearize those. I also want to list my linearized equations in a separate model block and force dynare not to linearize those. The reason i would like to do this is that the model is fairly large and complicated to log-linearize by hand. However, I have derived a few equations from the model first order conditions that I do not want dynare to linearize again. Thanks for the help.

Example:

model;

//all nonlinear equations

exp©^-gamma=exp(lam);

…

end;

model(linear);

//all equations that are derived as linear

x=rho*x+e_x;

…

end;
