Import personnalized newsletter to mailchimp : So I've coded a mailchimp newsletter with their code format.

But the problem is that when I import that newsletter, it don't gets on "drag and drop" mode but goes on "code your own" mode so we only can modify it with code.

I won't touch to that newsletter after, so I would like to modify it with drag and drop for the next ones who'll use it.

Thank's in advance guys.
