There's a poll option to allow users to vote on multiple selected items in a poll. But they still only get to vote once. Is there an option to allow a user to vote more than once in a poll?

For example, there's currently an interesting thread on what users are seeing for kWH/100 miles from OnStar. That seems like it would make an interesting poll, but if it were created as such a user could only vote for the last OnStar report(s) seen. Then they could never again vote as future OnStar reports come in.

For that sort of polling (presuming honest users, which for this topic doesn't seem unreasonable) it would be nice if a user could vote early and often. That way they could add new personal poll data as subsequent OnStar results came in.
