Hello,
Yes, to do this you need to create multiple links to Financial Dimensions in your row format. The first one will work in conjunction with your working company. The new link will be for your second company. Just make sure you are logged into the non-working company when you start adding accounts to the row. If your accounts are identical values you should be able to copy your existing FD column to Excel, remove all the characters (+, alpha characters, [, and ] ) except the account numbers, and past it back into the new FD column. Again, just make sure you are logged into your non-working company. This will cause your initial FD column to show plus symbols but it will work.
Thank you!
