I have a field collection group to which I am importing values using Field Collection Feeds Importer. This requires a unique identifier field within the field collection. This has posed an issue where the user has to keep track of these identifier fields. One way to avoid this is having an auto increment field so that when a new row is added it automatically auto increments this field without any user interaction. This would also help maintain the correct sequence at all times and avoid any user editing accidental mistakes.
This is how it is right now
Any ideas or existing functionality to use this.
