Move images with MD

Every Markdown document needs to have its own group? This will result into too many groups.

If I have two Markdown documents in the same group, the images are all in the same Assets group. If I only want to move one Markdown document to another database, I cannot move the Markdown document and the Assets group (which has the image of other Markdown documents).

So, this is back to my original request. To be able to move respective images with Markdown document to another database, similar to moving the respective annotation with Markdown document to another database.
