Feature Request: Automatic Category Assignment Based on Merchant History

When an expense is automatically created through an iOS Automation (Apple Pay transaction), Budget Flow currently imports the amount and merchant name, but the category field remains empty.

I would like Budget Flow to automatically suggest or assign a category based on previous transactions from the same merchant.

Use Case

Example:

● Transaction 1:

● Merchant: Carrefour

● Amount: €45.20

● Category: Groceries

● Transaction 2 (imported automatically later):

● Merchant: Carrefour

● Amount: €18.50
