when composite model can support DQ SSAS in embedded environment?

We have built an SSAS table model for business users to self analyze, but they have a need for secondary development. What I think is that the composite model supports secondary development, but the DQ SSAS composite model report does not support publishing to an embedded environment. What are the ways to support secondary development of SSAS+other sources? Or when does embedded support the composite model approach of DQ SSAS?
