Batch duplication does not create links

[Jon007]

Batch duplication does not create links even when "Allow linked duplication functionality?" is enabled.

This needs to be allowed, since it is almost impossible to create the links afterwards, since there is no searching or sorting in the create link dialog: if you have many hundreds of posts it is effectively impossible to find the post you want to link back to.

should be relatively simple to implement since the functionality already exists when duplicating a single post

[Jon007]

this could be done in mpd_bulk_action() bulkaction-mpd-addon l.158 after:
if ( $countBatch ) {

				/* JM: add persist links on bulk copy
				 * 		'source_id' : The ID of the source site
				 * 		'destination_id' : The ID of the destination site
				 * 		'source_post_id' : The ID of the source post that was copied
				 * 		'destination_post_id' : The ID of the source post that was copied
				 */
				$args = array(
					'source_id'				 => get_current_blog_id(),
					'destination_id'		 => $get_site[ 0 ],
					'source_post_id'		 => $post_id,
					'destination_post_id'	 => $results[ $highest_index ][ 'id' ]
				);
				mpd_add_persist( $args );

Although there is an action hook here which could allow implementation, the action parameters are insufficient to allow an implementation as the source post id is not available.
