Ability to accept Meeting Invites from other users in the mobile app

If I am creating a meeting invite within the Spark mobile application, it gives me the option to invite other users from my agency. However, if I invite those users, they have to go into the Web App to be able to accept that invite. I think it would be great if Real Time notifications could push when a meeting was sent to another user in the agency, and then they could have the ability to accept that meeting within the app.
