is there a way to make a schematic module show up in the form of a component to place it on a master sheet.  I am making an audio driver that has 8 identical output amplifiers.  I would like to draw it once and make a module with pins so I can just place them on the sheet. then when it annotates it will give each component in each module a unique designation to go to the pcb.  It makes the master drawing much smaller.  the individual modules look like components with input and output pins. an example is in Orcad when you place a sheet on a sheet.
