At the most basic level, the Template DSL component should be able to take the property added as a part of this story and serialize it accordingly.

For a nicer authoring experience, it should also be able to infer if it should be appended or prepended to the existing property on the asset based on the order of the JSX elements in the content. This is similar to how we are currently manipulating where the template property gets serialized to in the object with relation to the property it will be expanded to.
