Custom Hospitalization Treatment

Hello,

Just wondering if it's possible to create a new entry in a ModTreatmentsHospitalization.xml? I have created a custom 'regular ward' within a custom department, but obviously I need to create a custom treatment that refers patients to that new room. In case you're wondering, the custom ward contains more equipment to negate the need for transfer to observation or diagnosis. Feel free to suggest an alternative work around if the original request isn't possible.
