Be able to edit patient's chart ID number
When taking a new patient over the phone, you get some misspellings of their names, and the chart number is made from the misspelled name. The ability to edit the chart ID would be great so that the chart number reflects the correct spelling of their name.
More likely you would need to request a new chart ID on a case-by-case basis. I imagine that behind the scenes drchrono references everything by the chart ID.
As a last resort, you can create a new patient and move everything over.
