Possible Enhancement for AP match exception override page (PeopleSoft)

We have 2 department with access to Match Override Exceptions Page; one for AP and one for MM. In the match override page, it defaults to "O", or override action, reason and comment visible and editable. This is working for AP and OK to override - post and pay. But for our MM or buyer group, we want them to be able to select other option (not override) and enter comment without the system to post and pay. The MM comment entries is informational only.
