Allow Multiple Lookup fields

I’d love the ability to add multiple users or persons to a field.

Example use cases could be; 

- 2 (or more) CSM’s working on an individual company/relationship
- Multiple persons holding a specific “role” for an opportunity, e.g. Champion

The (front-end) functionality that is currently available in the timeline would be ideal. I appreciate it’s not that simple back-end wise though. 

@HollySimmons This should be a custom built field. There is a back-end task involved in it. 

Thank you for sharing this @HollySimmons. I can see how this can be very useful, we currently do not have this in our roadmap.

@everyone Please upvote this request if you have similar use cases(would be great if you can mention them on post as well).
