Hello, thank you for your feedback!
Can you provide a little more information regarding your idea?
You can always HIDE an account in the Accounts section of the top menu (click on your email address on top) when you don;t want to receive new transactions from that account.
So for example here - you add your personal bank and pull transactions from that and categorize the ones you want to Business. When you knwo all transactions it pulling is personal --> just HIDE the account.
Can you give some some more details Anita ? We want to understand what you are trying to do.
