If required, give editors the opportunity to customise the posts to be pulled out within a single post, basically replicating the "Articles Block" behaviour, now allowed only in pages.

See Alessio idea >> http://planet4.greenpeace.org/idea/allow-articles-block-in-posts/

Requirements:
By default, posts will have auto-generated Articles post (already happening)
IF
Editors inserts the Articles Block to customize related Posts, auto-generated Articles block must be disabled

Tasks

• Add field to override manually the posts to be shown in articles block
• Add this field in "Post Article Element" fields section (see screenshot)
• Test it replicates the same functionality ad the "Manual Override" field has in Articles block in pages
