You might consider setting up a character style for the red italics, and a shortcut to turn it on and off … or you could try combining the table approach with a character style. Example: I've applied a character style to the second column of a table, so that I can tab from column to column instead of reaching for a shortcut. Because it's a character style, converting the table to text and selecting – as the separator then gives me pretty much the results somebody requires.

A two-column layout would be easier to read and understand, I suspect … as well as being easier for you to prepare.
