I am not sure that room will solve you problem (or if it will be the best solution). I very very rarely use room and if I do, most of the time is for a multi-channel design. Why do you need to change the track width/clearance for every different IC? Normally you would use the same width for all (or at least most) of the signal tracks on a particular layer.
