User has a sub-account of a bank account that is used to print checks and wants the Print Checks screen to use this account by default.
As of now, this is not possible because if you select a sub-account on the Print Checks screen, it defaults to the parent account the next time you visit the screen. You can fix this by changing the sub-account to a standalone account that does not roll up to a parent account. To do that, open the detailed view of the account from the Chart of Accounts screen, clear the Sub Account of field in the Edit Account > General screen, and save the changes. Check CORE Help Center for details.
