Featured image in header area not working

Working with Catch Everest Pro. I have image sliders working on the home page (and throughout the site), but I'm wanting to have it that when a featured image is selected on pages and posts that the featured image takes the place of the slider on that page. I tried changing some settings, but it only seems to allow one image for use throughout the site. At one point, I was able to create a page template in a child theme where I replaced the slider area with a specific image, but that doesn't seem to be working now. Not sure if it was because of updates. Any help on this?
