When viewing entity, allow one click create new entity

When viewing an entity I often have the need to simply create a new entity with one click, that has the same parent entity relation.
Example: hierarchical entity relations of type ‘Page’. Without having to rely on the left column, or having to rely on a stand-alone view.

I can imagine the ‘new page with this relation’ to be a button included in the following dropdown:


You could define a button to achieve exactly this.

I see that my topic title and description was incomplete: I mean that when creating the entity, the user also gets redirected to the newly created entity named ‘New Page’ or ‘Untitled’.
If the dropdown option allows to insert a name, then the new page name shows that name already.
