None I know of. Changing proximity to the heat is easily done on any number of grills. Wood for cooking isn't warranted on some grill types, fine on others.
I've often had to cook on open pit grills. Can't say I'm a fan. I dislike having to attend so much. I don't like food cooked in flames, so one must constantly be on guard; moving to indirect means a rather long cook as there's no lid to contain the heat. YMMV, however.
