Display Configured Item On P3210 When Entering Sales Order

Does anyone know if there's a way to have the Configured Item Number in the detail section? Our client has multiple configured items when entering an order (see drop down). When they get an error in Order Entry, they don't know which Configured Item Number is throwing the error because only segment number and description show.

They have to go to the drop down and select each item number individually until the error shows. This takes a LONG time. With this form, you can't add fields with a Form Extension like normal Find/Browse or Fix/Inspect forms.
