Greetings,  
Is it possible to create associations in this manner?

```auto
tasks_repo.create({ id: 1, user: {id: 1, name: "Jane"}, title: "Jane's task" })

```

Not an Aggregate Write as the user tuple has an id and there is no combine.  
OR do I have to use change sets:

```auto
task = tasks_repo.create(task_changeset.associate({id: 1, name: "Jane"}, :user))

```

Also I was wondering if an aggregate update can be done with change sets and if you can give reference to examples?

Many Thanks!

Repo command methods are very basic and don’t support combined commands, so you need to stick to changesets.
