You don't have such an option with the associative model.
What you can do though, is to load your Brand field again in your Budget table, giving it a unique name throughout the data model.
Then, you'll be able to refer to the specific field, from the specific name.
Brand as BudgetBrand,
And then refer to the BudgetBrand field, that will contain the Brand values from Budget table.
Please let me know if you need anything else.
