Changing Tile Logo (Pre-define app) - Office 365

Does anyone know if it’s possible to change the logo of pre-definer app, specifically the SAML - Office 365. We need to use it for ActiveSync, but don’t want to confuse our users as we don’t use Office 365.

Is this something that Duo can do on the backend of us?
Is it possible to create a generic app that has the Enable Basic Auth feature?

Thanks,
