The model selector syntax is based on a common model root name, with a unique extension for each model. (Note: you may use the generic npn and pnp models for this exercise). Add a spice directive to load the LM324 part. In this case it is LM324. I was able to do this by exporting the data and using a Python script to optimize the parameters of the SPICE models, but it was a bit long-winded and so I decided to embark on a project to write a new GUI, as much for the exercise as anything else.
