Adding more insulation to the ducts will not help. The only way to solve the problem is to set the supply fan to run all the time on a low setting. Note that the heating setting can be set to delay the start of the supply fan for 15 seconds or so until the air handling unit plenum heats up, so that you don't get a blast of cold air. But, I don't think the cooling setting has a delay option, and it probably wouldn't help anyway.
