Logging and Loading a Virtual Bus

I have a big model that I want to separate it into 2 models, part A and B. I want to log the outputs of part A and load it as the inputs for part B. Both the outputs of part A and inputs of part B are one giant virtual bus. I would like to keep it as a virtual bus so that I would not have to change anything.

I have been able to use the method with logging a bus signal and then loading it back in a model referenced model. However, that requires bus objects, and the conversion to non-virtual buses was not successful. Basically parts of the model would have to be rebuilt or the huge bus object needs to be created manually.

Does anyone have any idea?
