Dawn Theme Background Collection Image

[YIW]

Any one know how to have this image change on each collection page? I used the below code in the base.css.

.section-template--18428917973292__product-grid-padding {
background: url(https://cdn.shopify.com/s/files/1/0739/9771/3708/files/4.png?v=1679512904)!important;
background-repeat: no-repeat !important;
background-color: transparent !important;
background-position: center!important;
background-size: cover !important;
}
