Edit Blog Posts created in Shopify

I would love to see the possibility to create/edit blog posts when they first get created in Shopify.
Right now, if I create a blog post in Shopify, I cant edit it directly in Gempages. What I would need to do is create a new blog post in Gempages, publish it and then in Shopify change the layout setting. But then i would have a second blog post (the one I created in Gempages) and duplicate content.

Right now, the best way to create blog posts is to create a new one in Gempages first and then publish it. I would love to have the option to do it the other way around.
