I am sorry that I am unsure of your question. Would you mind to share more details or even screenshot?
You open the question under Invoice group, also to see if is really relevant to it or not.
Someone than will might pick up your request and answer with more details.
Thanks adding details and for sharing those.
If you have admin access, follow the below path:
Admin - Expense - Expense Admin - Accounting admin - Select accoun codes - Search expense type - Update GL
Hope it helps 🙂
