Set the number of approvals required to pass a feedback request

I have been using codestream for the last 2 months. I have had the odd issue here and there but nothing major. The main reason I use it is so that I don't have to deal with hosting it myself. It also plugs directly into our bitbucket repo's without any issues.

1 suggestion though is, if you could set the number of approvals required to pass a code review. Currently its only 1 or everyone. It would be cool to be able to set that number per review feedback request
