No with the Wolf 36" range you select either a grill or a griddle they are not interchangeable.

I'd get the grill and a 7 gauge aluminum pan to use as a griddle across 2 burners .

I've had my Wolf range for almost 12 years and I have the grill and griddle. The grill much less functional (also just doesn't taste like a BBQ) than the griddle. If I had to choose again, I would go with a 6 burner with just a griddle or 4 burner a larger griddle. It is amazing to have a real griddle as opposed to using an aluminum overlay. Nothing like using what a real cookhouse has!

I posted this comment from earlier this year. I still agree with the functionality aspects of choosing the griddle, but perhaps my choices are not the norm.

After using the griddle several times per month for 14 years a basic wear and tear feature (gas valve) of the griddle broke. Keep in mind: It was a $450 repair. Amortized, probably still not a bad deal. Oh how we love this griddle though!!
