How to add classes in Upfront to use animate.css?

The “animate.css” (https://github.com/daneden/animate.css) style is enqueued (via mu-plugin) on the Upfront powered site. This, however, requires additional classes to be added to elements that we want to animate. How to do this?

We can create a preset and its name will be used as class name but how to add additional classes like for example: “animate bounce”? If we use e.g. “infobox animate bounce” as preset name, it will add a single class .infobox-animate-bounce instead of three separate classes “infobox”, “animate” and “bounce”. How to achieve the latter?
