I want to add ID numbers to the account names so that they are easier to view and manage without the sub-account user seeing the ID.

If there was an agency name view (you can rename the sub-account internally to the agency), that would be great.

Or some other way of sorting sub-accounts better in the dropdown menu.

Agency View:

01 - Sub-Account Name

02 - Sub-Account Name

Sub-Account View:

Sub-Account Name
