Hi all! I've added a new subsidiary and need to add all the accounts that are available to a different subsidiary to this one. This new sub is not a child of the existing sub. What is the best way to do this in bulk? There's 730 accounts to enable on the new account and that's a lot of manual clicking!

You can update this through CSV Import update to the Chart of Accounts. It's a little tricky getting the format of the imported cell where you have multiple subsidiaries but also not impossible.
