Sure, I usually just dump them to one side or the other, and one chimney should get you where you are wanting to be. ThrRoff has multiple vents on the underside of his as does one of my kettles but if you are getting a new one (one touch) you will have one large vent on the bottom. Mine is usually open and I control with the top vent which is designed for this purpose and has a comfortable cool grip. Rarely do I need to get lower and need to begin closing the bottom vent as I use my bullet for that stuff anymore usually. The kettle is easy to get and hold at 350 as these guys say, just burn down a chimney some till it gets there then just add fuel as needed. You could also use a water pan as a thermal mass to level off heat spikes. Remember though you're cooking with charcoal/wood in this and you will get variance. It's an art.
Good luck and have fun with your excellent new purchase
