Image gallery for carousels that scrolls independently

Right now, you can have a list of scrolling "image gallery" indicators in a carousel (e.g. in https://support.replo.app/articles/1751369744-create-a-carousel-with-custom-scrolling-indicators), but you can't have the gallery scroll independently from the main carousel.

Would be nice to have a way to enable this and a guide on how to set it up!
