[WM] Loop de Loop - looper

Not that experienced with WM, have been prompted to have another look at it.

I want to create a list of Orders and Order Details...

Order No: 1234
Customer: John Smith
Milk 2 L
Bread 1 loaf
Potatoes 1 Kg
----------------------------------------
Order No: 1276
Customer: John Jones
Cola 2 L
Rolls 2
Carrots 1 Kg
Eggs 1 Dozen
Fish 1 Kg
----------------------------------------


...is it possible to create this style of list? I have previously used a LOOPER to create a list, but don't know if it is possible to have a LOOPER within a LOOPER, or if there is some other control, or method to achieve this?
