Custom attributes on Account dimension members

Content

Is there a way to create custom attributes on the Account dimension like there is on the other dimensions in TRCS? When I go to the custom attributes screen when looking at the Account dimension, there is no option to create a new attribute.

The client would like to have custom attributes on their ledger accounts, so that they can store the equivalent sub ledger account information and potentially information such as Tax Reference numbers or bank account details.
