There is likely an attachment point you can use up on the center support for your damper. You just have to make sure you do it in a way that doesn’t affect the operation of the flap. One fun thing to do is have a stew pot that is refrigerated or outside much of the time that gets broth, veggies, game meat and other ingredients added to it as it gets consumed, forever changing but always on hand as a hot meal. Sometimes you have to change pots and you just need to be wary of repeated heating and cooling and its effect on bacteria growth. Basic foodsafe principles.
