Is there a program that you can add your announcements to?  Right now I'm doing it on a powerpoint and have 9 slides.  

See if this is what you are looking for.

That said, we still make ours in PowerPoint and export them as an .MP4 video file. We import that into EW, set it to repeat, and run it from the schedule. We've been doing that for 7 years or so.
