Adding multiple text overlays to video Nero 2015

Hi

I finally upgraded from Nero 7 to Nero 2015 for my new pc and am amazed at the difference. I have made a video and would like to add text overlay captions at various points in the video itself but I can only add the initial text and it does not seem to want me to add another.

Can someone tell me if it's possible to add multiple text overlays to videos using Nero
