OpenXml manipulate bulleted word document

I have an existing bulleted line in a word document like this:

- Condition1

I would like to add text on the next line with the same bullet like so:

- Condition1

- Condition2 etc.

I am currently using C# and have a line such as the text below but don't know where to go from here - I have tried ParagraphProperties.CloneNode() but without success. 

run.AppendChild(new Text("Condition2");
run.AppendChild(new Break());

which gives me this:

- Condition1

Condition2 (without the (-) bullet)

Any help would be appreciated.
