Acuity scheduling for multiple attendees in a single meeting

I need to schedule meetings with more than one person. When I add the additional email address, it adds that address to the first person invited. Example, I set up a meeting with Sam and send it. Sam wants Carrie to attend. In Acuity, I add Carrie's email address to the event. When I look at Sam's client profile both addresses are listed and associate with Sam. There MUST be a simpler way (and please let it not be setting up a class). This is a very ordinary use case.

Is there a workaround? We use Google mail, if that makes a difference.
