Well, yes, or you make sure you can do that stuff yourself by actually doing it instead of leaving it to an agent. If you have to do it often you can leave some to agents but still do a few yourself so that you keep up to date and also can check whether what the agents do makes sense. You'll still save time, it might not even cost you any real time if you can handle a few cases while the agents take care of the others and you both finish around the same time. The agents may have done 10 times as much work as you did in that time but since you'd otherwise just have been waiting for them to do their thing you're not losing anything while you gain (or keep) experience.
