How to add list to Marquee

Hello I have a number of messages that are in a list. I want to display them one after the other but he lets me insert only a string. Is there another way to display the list line by line?

The issue names the Marquee widget but no file, test, or entry point. Start by locating the widget's string input in the repository and determine whether list-by-list display is already supported; done means a clear supported behavior or an explicitly defined change.
