Multiple Materials Object Baking in Cycles

Hi, I have a single object with multiple materials and when I bake I can’t find a way to bake only the material i’m interested in instead of baking again the full object with all the other materials. Is there a way to select which material to bake?
By the way, baking in Cycles is very slow for me. A LOT of times slower than a very nice render.
Any advice on this? Thanks :slight_smile:
