Which while not the drawing above is at least more than the standard generic part. To create a part with the drawing above you would need to create a new custom part by editing the schematic svg file with an svg editor such as Inksacape. In this case I’d probably start with this part as it has all the needed connectors and formating already done for you and all you would need to do is edit the square boxes in the svg to logic symbols. To get those logic symbols you can use copy/paste from other parts (I think most of the shapes are in the 4000 series parts posted and now in core). With more experience in parts making you could (or I could) make this in to a schematic subparts part where each individual gate can be moved by itself (this has performance implications however, a lot of them makes frixting slow). Last you could post your work here so others can use it as well.
