Create a poll in Paper

It would be great if there was a bullet-like feature that allowed others to upvote/downvote each line. This is sort of like a poll, but not mutually exclusive.

My use case is a long list of agenda/meeting ideas for a company retreat. We're doing a sort of mini-university where people can offer to train each other. If we could upvote line items, we could see which courses were the most popular and be sure to host those! we're currently using comments with emojis, but this gets pretty cluttered and hard to track.

The ability to reply to a line with emojis, especially if there were emoji counts (think slack), would also do the trick.
