Shipping label shipping date

Hi,

I am wondering is there any possibility to add a shipping date field somewhere on the shipping label? This is definitely the required feature as many consumers will want to change their shipping date especially if they are preparing everything a day before. Currently, as I see it, it generates a date by getting the current date.

If you have any recommendations for me of how could I implement this feature it would be much appreciated? So I don’t need you to code it for me but just give me any hooks, classes, functions in your plugin that could help me to get on the track with it.

Kind regards,
Boris
