Yes, you can create a single schematic component (with a single footprint) that has separate child symbols representing each of the independent parts within the component. For instance, a single LM348 contains four discrete 741 op-amps in a single SOIC package. After you add/create the new LM348 component in your schematic library, choose "Tools > New Part" to create a child symbol. You should see Part A and Part B listed under the new component. If you have a triple or quad package part, you can select "new part" again to add the additional Part C and Part D parts if necessary. Under each of the discrete parts, you can draw the required symbol and assign pin numbers. Typically the +V/-V/GND pins will be included on the "Part A" portion of the component only. When you go to place the part on the schematic, it will place a U1A on the first click, followed by the U1B, U1C, etc for each child symbol. When you add a footprint to the component, it will be applied to the entire group of parts. And when it's added to the PCB, it will place a single U1 component.
