you just created, you can use the 'Load' button in the dialog box to load a file (model or .subckt definition) for the symbol. When creating the netlist the device_model is dumped into the netlist only once, even if you have multiple instances, like this:
The section between the ** begin .. ** end sections is the device_model attribute. There are other ways, for example you might want t create an empty schematic with just the I/O pins, and insert a 'code.sym' symbol with the definition of the schematic expressed as netlist code instead of drawing the actual circuit. The advantage of this first approach is that you don't even need to have a schematic view, you only need a .sym view.
