[Suggestion]: Being able to add polls at a later time, or being able to add polls to comments.

The title basically explains it, but the concern here is that if you have a post, and later want to add a poll to it, you have to remake the post (from what I understand). I think it would be useful to have an edit tool that allows you to add the poll to a discussion later, or perhaps even to comments so you can have multiple polls on different things, almost like a wider survey.
