Display Patient ID

We are migrating from legacy software to PracticeHub and it would be incredibly helpful to be able to see the patient ID of patients that have the Custom Reference field filled out. As we need to use this ID for reference to the legacy software.

Note: You can only see the patient ID when the Custom Reference field is blank.

Most of our patients are using the Custom Reference field so there is no simple way to get to this data out of PracticeHub.

I would be great to be able to add this field (and others) to the Patients page so I can extract the IDs for all patients which match a tag for example.
