I am able to create multiple objects using the bulk operation within a transaction. However I have to iterate over each object with a separate API call if each object happens to have a relationship with another object. While the deep save API solves this problem if all I’m doing is creating these objects, there are many instances where I actually want to link this bulk creation + relationship setting alongside other operations within a single transaction. However, I haven’t found in the documentation whether this is possible (if it isn’t, could this be a quick(ish) feature request?).
