Using Nintext 2013 - I have a hierarchical list of Distribution groups with a multi-value lookup field that contains parent distribution groups. I also have a list of individual contacts with a multi-value lookup field that contains which Distribution groups they are members of.

I created a multiline variable to record each selected distribution group name and the full name of the associated individuals. I then drill down to an find any child distribution groups and that group's associated individuals.

I am concatenating the multiline variable in Build String action then using the final outcome as the Content Control value in an Update Document action

I want to be able to indent text but adding multiple spaces did not work

I want to have better control over the line breaks that are being added, even running regex to remove multiple concurrent line breaks did not resolve

Is there any way to add more format controls in the build string?

See attached examples of what I want and what I get
