You can make sure that a recurring transaction is always categorized to the same category and then that the money is taken from that “envelop” based on the category.
So my rent payment will always get automatically categorized to rent, and then all transactions in the rent category automatically pull from a specific “envelop”.
Envelops are just a UI/helpful budgeting thing; it’s not an actually different account.
Do you categorize the expense or is it automatically categorized to the correct spending envelope?
