Removing Reverse Batch Button from Enter Journals

All,

I have a customer who wants to remove the Reverse Batch button from the Enter Journals form for only posted journals.  I have explained to them that the recommended approach to remove the button is to use function exclusion on responsibility or custom menu.  However, this process removes the button from form but for all journals both posted and unposted.  Is there a way using Forms Personalization to remove the Reverse Batch button only on posted journals?

Any information would be greatly appreciated.  Thanks in advance.

Thanks & Regards,
Andy
