Currently integrated scheduling is only supported via transformations set up in the UI. Transformations set up in the UI allow for no customization of the command that gets run, which is simply `dbt run --models +the_model`. This does not run seeds. It would be great if this could be `dbt build` instead. Or even better, if it could be customized to whatever set of dbt commands we want. Even better, allow full access to the runtime (docker image customization, etc.).
