Keeping track of what content items have assets can be a daunting task. That's were our attachment(s) column comes in handy.
The Divvy Details
Within our Content Interface is the option to select the Attachments column from the Edit Columns dropdown.
Content Interface Attachment(s) Column
Once you've select the Attachments column and apply it, you will have an additional column for each content item in your Content Interface view. This column will contain a paperclip icon if the content item has a attachment(s) associated with it, and be blank if it does not (screen below).
