Specific Relationship Tab Views per Item Type


I am working on trying to setup relationship view tabs for 2 item types. They share a relationship with another item type. I would like to customize the grid that appears for each type.

Example: I need to use affected item on 2 item types that have workflows.

When I add it to the relationships tab for each, the grid display is the same for both however I need one set of properties to display on one item type, and a different set on another that can be filled and saved (i.e. disposition, comments on one and duration, units on the other).

Any help would be appreciated.
