For the Mitel Assistant, could it be made possible to customize what field the Assistant app references in a user to determine the phone numbers?

We have customers with a very fleshed out Active Directory that they sync up to Entra. When they sync it upward, they sync the 'ipPhone' attribute to Entra, and has been used to setup CloudLink integration. The 'telephoneNumber' field is synced upward as well, and applied to the "Business Phone" field in Entra, is populated with their DIDs, and this is used to populate the user's contact card information for email signature creation.

Mitel Assistant uses this 'Business Phone' field as the primary number to call when you search for a contact, and you cannot even see the extension the customer syncs up, since you have no way to make Mitel Assistant look for another attribute field.
