Print TIcket arranging by CATEGORY

Hi
To show category of product we us {GROUP CODE} tag..

TAG WORK but non as expeted.

In versione 2, there was GROUP TEMPLATE that make group of product...

For example if i order a caffè and a cappuccino in v.2 it print

Coffee Shop

- 1 Caffè

- 1 Cappuccino

Now in v.3 it print:

Coffee Shop

- 1 Caffè

Coffee Shop

- 1 Cappuccino

How can i do? I need grouping and not only the tag!

Also is possible if i add a product and print the now ticket to have to partial total,

like 1,00 euro, and total of the table like 10,00 euro? 

Many thanks for this great and beautiful APP!
