Ability to customize the wishlist icon and import new one

We would like the ability to replace the default wishlist heart icon with our own custom icon. This should apply consistently across the storefront, including the product page and the menu.

Having a built-in option to update the wishlist icon ourselves would make it easier to match the wishlist design with a store redesign or brand refresh, without needing custom support or manual workarounds.

If this would be helpful for your store as well, please upvote this request!
