How do I setup everything under a fixed snowflake Schema?

[jasonsross]

In my org we have to work within fixed schemas. We might have 2 schemas, one for prod and one for dev tables, but we do not have permissions to create new schemas. How can I setup sqlmesh to do it's magic all within a single schema that already exists, ie snowflake_db.some_schema.[all_sqlmesh_tables/views_here]?
