QB Issue Resolution:

The “Identifier” or Field becomes available Everywhere, because you checkmark where it is “in use.”

You need to Populate that with the selection you intend to use it for, and that would be done using Add/Edit Multiple.

Using one of the provided fields works better, if it meets your needs. For instance, Customer Type and Job Type are better than a custom field, since they show for lots of reporting options.
