How to change name of personal meeting room displayed in waiting room

When someone enters the waiting room for my personal meeting room, the topic says "[My Name]'s Personal Meeting Room." Can I change the meeting topic to something else? I saw the tip to schedule a meeting using my personal room, and name the scheduled meeting whatever I want. That did not work for me. My waiting room still said "[My Name]'s Personal Meeting Room." Also I'm hoping there's a way I can do it without having to schedule meetings. Thank you!
