Append to text doc from template smartservice

Question

Hello Community, 
 U want to use a array of CDT's as input to the text from template smartservice. It works fine for 1 Line. How to configure the next CDT's Will append to the document on the next Line? Tried joinarray char 13 and char 10, this only works for one mergefield. 
 Kind regards, 
 Erik

As far as I know, you should be able to insert char(10) linebreaks into a text-from-template document and get linebreaks in the resulting text document. If you have a dynamic number of rows you want to generate in the document, you would probably need to use one merge field and use an expression rule to handle generating the text that you want to populate into it.
