Often one does not need to draw a symbol. For example, opamp-1 and opamp-2 in the default library have the correct pinseq attributes for a 5 pin opamp subcicuit conforming to the defacto industry standard pin sequence. So one easy way to proceed is attach a model-name attribute to the symbol instance and include the model file.

Just remember to check pinseq attributes against the model. If there's a problem, make a private copy of the symbol and fix the attributes. But even in that case, you need not draw anything.
