Limit the items a supplier user can search for and add to affected objects section of a change reque

Summary:

Limit the items a supplier user can search for and add to affected objects section of a change reque

Content (required):

Our client does not want the supplier users to search for all the items from the Affected Objects area of the change request form. They should be able to search for items they have been given access to. Is there a way this can be achieved?

Item class security will be too broad to accommodate this requirement.
