Slidable Content over Image

I’m wanting to have a very simple slider of background image with 1-2 lines of text and a boldial-styled button over the image. Currently when I use the page builder and create a slidable element, it put the image above the content. I know I can set a row background image, but I’m needing a different image for each slide.

Using a Slidable element, how can I get my content to show up centered over the image I want as the background for that slide?
