Auto include Delivery Date in Order Note

First of all I would like to thank Pixlogix for the excellent plugin!

I’m currently facing a situation, hoping the gurus out there can assist.
Currently the mobile app for Woocommerce does not support additional fields to be displayed, hence the delivery date will not be shown in the app.

I’m thinking whether is there a way to auto add the delivery date into order note when the order is created so that our team will know the delivery date from the Woocommerce mobile app instead having to login to WordPress backend.

Thanks in advance!
