RE: CMT Remapping

You can slice the data set as needed using IGNORE/ACCEPT options. For analytical ADVAN models, you often do not need CMT item, and if needed, you can introduce extra columns CMT1, CMT2, CMT3, and CMT4, for each of the 4 drugs, and CMTALL for the combined model. So the only thing that would be needed is to re-code parameter names and theta-eta-eps indices when you combine 4 models in one. This step would be needed any way.
