JCC import error if the ID & Description for CC do not match master list ID & Description

This would come in handy in the given scenario:

If the client is trying to import cost codes via the Excel import onto a prime contract (the job cost codes) or trying to manually add an item to the contract, it would be nice to have an error or message indicate to the client that they are trying to create a cost code ID and description that does not match the master list cost code ID and description. This would help the client from accidentally creating new cost codes that already exist on their master list.

Currently, there is no error message if I try to import a cost code (via the Excel import/manual entry) that has the same ID or description.

Added benefit this will also assist with clients who are integrated to different ERP systems.
