Shopify draft order manual booking metadata

When a customer using appointo to book an appointment the time and date of that appointment is attached to the order as a metafield data hook. When making a manual booking through appointo app it does not do this so when looking at the orders we dont know which order is for which date. If this could be added simply that would be great as our company and many others would benefit from this. Please see screenshots attached with red arrows pointing to the area.
