Allow multiple people to book a Meeting during the same time slot

My need is slightly different, but somewhat similar. I would like to be able to add multiple attendees to a meeting booked through a user’s meetings link. OR, I’d like to be able to see a user’s availability when I schedule a meeting through the Meetings creator on a Company record. This allows me to add multiple attendees, but I can’t see the user’s availability’s through this option. One of these two solutions would be ideal.
