Edit a post awaiting moderation

Hello,

I have moderation required on all posts but I cannot edit a post that is awaiting moderation form the front end. The edit button is there but it will not allow me to edit the post until after I approve it.

This is the whole reason I want to have moderation on my forum, so I can change things before they are posted.

Please advise how I can accomplish this without doing it form wordpress back end.
