Change customers forms

Hey everyone,

I have some questions about the forms in the shop.
We have a problem that people don’t understand the address line in the form; they forget to write down their house number.

Is it possible to change this address line in to two fields in the form?
If I click this part of the form it says: “Delivery Data
These fields are automatically updated based on your customer’s cart and location.”. I can’t find where I can change these.
I also want to change the order of those fields cause postcode has to be above place but can’t move anything.

Anyone got a sollution?

Greets,
Geijs
