Adding a paragaph after every paragraph

[DBDigital]

I have a interesting problem. I am trying to add a paragraph after every existing paragraph except if the line contains a bracket. Is there a way to do that?

I know if I search for $ with a replace of \n it will add paragraph another paragraph after every line but I want it to skip any time that there is a bracket in that line. I assume that is possible?

Use two passes: 1) search for paragraphs that don't contain a bracket, then 2) add the paragraphs ONLY to the matching paragraphs.
