Even if you pick classroom, it still does not allow our client to click and schedule a meeting directly in their calendar and invite more than one person at the same time.

Ex: In Real Estate, you want to invite both husband and wife ( or ex's) at the same time to a meeting or a property visit. How come we can't invite more than one contact at the same time and why can't we add more the one user at the same time. It's what everyone is used to do in other planning tools, and a reccurring questions/unsatifactions we get from our clients. Thanks in advance! :)
