Editing and Moving Items in an Additional Field List
A user with the List Admin permission can edit an item in a list that has been added to the default Contract, Company, or Project Profile screen. The List Admin can also move a list item to change its position in the list if the default alphabetical sort order is not the most appropriate ordering for the items in the list.
A linked field, tree field, and person field that has been added as an additional field to a Company, Contract, and Project Profile can also be edited, disabled, and deleted.
