Work models as base models for other work models

Related products: Software Factory

We already work with base models which consist of tables, subjects, variants, etc. to create base modules, which can be implemented in other work models. When developing these base models, it is difficult to test your own work, since base models cannot be run seperately. The workaround for now is to connect base models to work models and then shift them back to work models. The connection stays, for now. 

We would like to see the possibility to use other work models as base models for other models. 

Can you think of a future proof solution?
