How do you add a custom field to the order in Minishop2

Hi hopefully someone can help. I'm looking to add new fields to the order form on Minishop2, I have updated the Lexicons and have everything seems to working on the front end, but I can't figure out how to pull it onto the order form in the manager

Any help would be greatly appreciated

Hi,
Could you please give me some more details..how exactly do you use it? I've added custom fields many times..just let me know your idea and I'll show you how. What fields do you need excluding basic ones?

If you can that would be great, I'm just looking to be able to add a customer number and shipping address for the good's, as in one lot of fields of customer address and the next for shipping
