Rename Display Name of My User as a Guest

I need a way to programatically rename myself as a guest (not the host). This could either be by a keyboard shortcut to pull up the rename dialog box, the API, or I could (worst-case scenario) create a web app using the Web SDK.

The context of this is, If I have multiple people on one physical room joined to a meeting as a guest on a single device, the display name for their account represents the entire group (e.g. The Smith Family). However, when raising their hand, only one of them is meant. I would like to programatically change the name to the person that is raising their hand.)
