Additional Fax users under main account

Account type: US
A brief description of the business: We are an insurance broker
A high level description of the product or feature being requested: Currently we are limited to only 25 fax users under the main account. This needs to be expanded to 100 or more. The reason for this request is because if I create another user and put fax users under that user I am unable to select the appropriate fax number under the fax cover page. It shows the ring central number. A ring central rep told me only the main account can display the correct fax number. This is causing an issue because more than half of our 60 employees are sending faxes out with the incorrect fax number on them, and when the client tries to fax back it rings on the ring central number. As far as I know there is zero reason for this limitation. There are multiple solutions to this issue, either allow us to import fully customized cover pages, increase the main accounts fax users to 100 or allow new users to have the main fax number as a choice under the cover page.
A typical use case scenario explaining how your business would use the feature: Our users would be able to send a fax with the correct information on the cover page.
Benefit of such feature: Correct fax number on the cover page for more than 25 people.
Number of Users and/or Digital Lines: We have 1 user and 60 employees. We only use this for faxing not for phone calls.
