Link workflowtask comments to the workflow object

Hi all,

Let's take an example. I have a workflow to validate a quote. First state is "redaction", then you can transit to "ask for validation". There, a separate approval task is generated.

The comment leave during the transition state from redaction to ask to approval is linked to the quote object and can be displayed in the core of the task.

But, the comments leave when the task is approved or rejected is linked to this task, not directly in the quote object. It is not very clear for users to understand why this quote has been rejected.

What are the way to either copy the task comment to the quote object comments or to display the task comment in a notification (which would be send to the person who transit from redaction to ask for validation).

Many thanks in advance to all experts here ;-)
