Office challenge: How to use input values as default values in an Access form

Let’s suppose one of your users transfers data from paper forms, usually submitted in batches, into an Access database. That means a lot of the data - salesperson’s name, territory id, and so on - repeats across the entire batch of forms. These aren’t true default values, not in the traditional sense. However, the user would like to input them once, and have them remain the default value as he inputs a record for each form in the batch, as if they were true default values. Could you do this for your user?
