Create a Model without API_NAME

Hello,

I am trying to implement a process flow in APG which should create a new model.

There is a predefined Service for that (Create 1 Model), which requires a model type.

This Type should be given by the API_Name (e.g. MT_EPC).

We have derived model types and they do not have an API Name.

Is there a way to create such a model in any other way, e.g. using the GUID of the model type?

Regards,
