Changing default "mobile" contact within an opportunity "whom to deal with" summary view

Changing default "mobile" contact within an opportunity "whom to deal with" summary view

In the new version of the Zoho CRM, there's a new "Whom to deal with" summary/ quick view in the top right corner view of an opportunity, which includes name, email address, and mobile number (which we love).

Is there a way to edit/ change the settings so that this "Who to deal with" view reflects the "preferred phone number" and not always the "Mobile" phone number, as seems to be the case.
