Add +1 in event RSVPs❤️‍🔥

Right now events RSVPs are only limited to participants. We have a parents' organization where we need to have RSVPS for parent, sometimes a +1 adult, and then also kids. So we needed tiered RSVPs and the ability to add +1s. Can you please implement this feature? Otherwise we'll basically have to use eventbrite or some other platform to facilitate our events.
