First, you have to creat a new detail sheet. (icon is called "new detail sheet") It's a little white rectangle, with a circle in the uppe left corner. You find it by pulling down the "new sheet" icon, which is a plain white rectangle.
Next, you use the function called "instantiate 2D component." The icon is a little blue circle with 3 arrows, pointing to 3 red circles.
This will allow you to reuse details from your detail sheet.
Your boss should consider about giving you some kind of admin training. The money he will "save" for not training you might ends as the money he is losing because of wrong methodologies.
