Order Revision and Text entry

Hi

When Activating  Order Revision functionality in P4310 (Order revision tab)  with Text entry Allow, this display a Text attachment  functionality once revised.

Thing is this  text attachment is attached to the Header Attachement of the Order

So if  an Header attachement already exist, it will pops up the existing one for adding comment

Does any one  ever did a customization to  have this text entry enable and not pointed to  header attachment (MOB)?

Or  any other trick that  could  allow us to have a dedicated Text Entry (independant) of the Header itself?

Thanks in advance
