"Version History" for items within Workflow

Whenever a workflow item is abandoned, we have to rely heavily upon the comments left during approval or rejection to know what changes were made since the last iteration. I propose that every time a workflow item is initiated, Sage CM will capture a snapshot of the item as stood when it was approved. This would show line items, values, JCCs, etc. As an item is abandoned and revised, users could directly compare against past version histories for a definitive and comprehensive understanding of what exactly has changed in each iteration of the item.
