Allow attendees to identify if they're attending on behalf of employer

Problem/Motivation

On my profile, I'd like to list my current position and employer. But this does not mean I am attending as and representing my employer.

That way when my session is displayed on the website or promoted and my employer is a sponsor, it doesn't appear that my session is part of their sponsorship.
