I can think of many ways to do this, and maybe the most straightforward approach would be to create as many copies of the title as there are rows and then place them back-to-back on the timeline.

Start with the normal title, then in the fisrt copy bold the text in the first line and adjust the starting & ending points to match the narration.

Do the same thing for the next row in the next title copy, like this:



I chose to bold each line, but you could instead highlight the text border, add a shadow or add a backdrop all within the Title Designer. Download the sample project from here to get a better feel for how to make these edits.
