On Opportunity and Sales Order (accounting seed object) we have related list called Opportunity & Sales Order Attachments. This list of attachments is shared between Opportunity and SO.

Issue:

We attach many documents during making and approving before Sales Order is created. Many time there are many files and they become irrelevant once Sales Order is created. I do not want to delete them.

Solution:

I want to archive them or move them to another section. This Archive should be on Opportunity only. Do not show on Sales Order. See below and idea to redesign attachments as one related list. If that does not work separate them in to two.
