On the new transaction tab, you could add a button that populates pre-filled data, allowing you to modify, for example, the price.
For instance, you could have a template for recurring but unmeasurable purchases in a specific store. In this case, all the data would be filled in, and only the amount would need to be changed.
It should include all the data required for a new transaction and be pre-filled so the user can then modify the data as needed. The date and time should reflect the moment of the new transaction.
