I may be wrong, but IIRC, there's no way to do this through the API. `@@` is not very well supported. [The parser](https://github.com/beancount/beancount/blob/eb8be17c750257dc693e3173c30d2cabc9ab2faa/beancount/parser/grammar.py#L868) has it but the [Posting class](https://github.com/beancount/beancount/blob/eb8be17c750257dc693e3173c30d2cabc9ab2faa/beancount/core/data.py#L206) doesn't.
For what you're wanting, shouldn't you be wanting to _avoid_ using `@@`?
