Create option authority to leave parcel on Delivery Methods section

[Jolsvi]

Hi,

I'm just wondering is there anyone had modified the Delivery Methods section like this:

- Adding option to customer if they want to provide permission to leave their shipment when they are not at home.

- Section will be underneath the delivery method like "Leave a message"

- Once they checked the box / choose that option , form will posted the text status "Parcel to be left at premises if no one is available to accept it." in the database (ps_address).

I'm still beginner in programming. Hope someone could help me with this modification, please.

Thanks in advance
