How can I define Multiple reference models ?

[tkinte]

Hello. I wonder if it is currently possible to define more than one reference model. In some cases, it could be interesting to define several reference models. This could particularly be the case when the company is a large group with more or less autonomous branches and significantly different "core businesses". In such cases, it could be interesting to define branch-specific reference models, with or without the possibility of linking these different reference models with a global reference model.
How can I do it best?

Thanks in advance for your help.

Best regards.
