@javapro13 Your assessment is correct - you can only dedicate one bank account to an individual property if you want to automate the process. You can easily create individual cash management accounts through Stessa if you want to smooth out the process - 1 account per property. Yes it would require a little bit of a effort to set up.
To connect a bank account responsible for multiple properties, add the account, then do not assign (Select “None”) the account to a specific property. This will then have the transactions queue up in the “Needs Review” tab where you can assign to the appropriate property as desired.
