How to share transaction between multiple repositories?

[enheit]

Is it possible to achieve something like this with the current API?

let user_repositoriy = database_manager.repositories.get(UserRepository)
let another_repository = database_manager.repositories.get(AnotherRepository)

database_manager.begin_transaction()

user_repositoriy.save(user);
another_repository.save(user);

database_manager.commit_transaction()

I want to hide sqlx under the wrapper to remove hard dependency to sqlx
