Ability to add images via "edit post"

As a Steemit user, I would like to be able to add images via "edit post" or in other words, add or update images in a post I've already published so that I may improve or fix my post after I've posted it.

Currently, I can only add images to a NEW post.

Note that my screenshot shows the functionality for a "NEW" post. I couldn't upload a second image to show how the "Edit Post" functionality currently works (trust me, there's isn't an option to add images).
