After adding a block to a content area with "Create new block", and saving the block, the block is closed, and the editor is returned to the page with the content area.

The block itself also contains a content area. It is not possible to create child blocks in this content area until the block is saved,  i.e. "Create new block" is not visible until the block is saved. For that reason I would like the editor to remain in the block after saving, to be able fill in the additional fields, including the content area of the block which was just saved. 

Is it possible to enforce this behaviour programmatically?
