[SLDEBUG] How to speed up the process

Hello, I'm working with SIMULINK on a big model that contains several hundreds of modelReference blocks and I want to compute the execution order of these blocks. I'm currently running the SLDEBUG utility with the command line interface

    cmds = {'slist', 'quit'};
    sim(model,'debug',cmds);

Depending on the model size and number of referenced models, this process can take a very long time (~4h) and iterations can become very expensive in terms of development effort. I understand that SIMULINK needs to build the referenced models first, and then link them to the parent model =>### Successfully updated the model reference SIM target for model: model name

Is there a way to fasten the process ? Is possible to get an execution order without compiling every referenced model and linking the objects to the parent model ?

Kind regards Michael
