Ability to order Open Questions by the number of comments

To help us work through our crowdsourced content, is it possible to order the questions raised by our users so that we can see the questions with the most answers first?

Currently, with the Admin page for Open Questions, we are unable to see how we can do this? The number of answers is shown, but you're unable to order by that value.

Being able to order by comments would be useful because:

1. If an Open Question has a lot of comments it is probably ready for us to review and turn it into a new QnA.

2. If an Open Question has no comments for a period of time it could be because the answer may be unknown or the query needs reviewing / promoting in some way.
