Related Items - Supersession Requirement

Dear all OM Experts,

Need your inputs on the Oracle Order screen behaviour for Item supersession requirements. As per my understanding if Item A is having 'Superseeded' relationship defined with Item B the in the SO screen  When I enter the Item A and tab out, the related item window opens and shows option to select 'B'.  In this scenario Item B replaces A on the SO line.

Now  I am looking out for standard functionality to handle one to many or many to one 'superseeded' items. e.g. Item A is superseeded by Item B and C then is there a way to dsplay both B and C on the Order screen 'Related Item' window?
