How Do I Add Numerous Images To Thumbnails In Pages On MacOS?

I’ve been using Keynote for years. One of the nice features is the ability to drag and drop image files into the thumbnail pane, which results in each image becoming a slide. Saves a lot of time as opposed to dropping images onto individual slides one at a time.
I was hoping with the new thumbnails view in Pages, the same thing would be possible. That by dragging and dropping my images into the thumbnail pane, that each image would become a page of my document, but it didn’t work.
I’m wondering if it actually is possible, and I’m just doing something incorrectly, or if there is a different way to accomplish the same result. Such a shortcut would save me a substantial amount of time. Thanks in advance for any help.
