Associating event with hosting business and venue

Hello,

1) I’d like to associate each event with the business hosting it and the venue. Many events are online only. Venues could be a physical, like a convention, or websites.

2) I’d like certain event fields pre-populated for each host; so they can click “new event,” pick the kind of event (most are CPTs), and just enter the info that changes from event to event of that kind.

3) I’d like each upcoming or current event to automatically populate in the host’s detail page.

4) I’d like venues to automatically list all events being hosted there.

5) I’d like to think that what I’m asking for is easy-peasy now that we have the amazing V2!

Thanks,
Steve
