Gallery Listing Widget Custom URLs

The Gallery Listing widget should be improved for Custom URLs. Currently it works to use Custom URLs and the lightbox slideshow as long as the checkbox for "Box Link" is not selected, but then the link only works on the title/caption. This is should be the same link for both the title and box links. If you check "force custom URLs" then all images that do not have a custom url are blank and the lightbox is empty. I would expect the custom URL to simply override the default (media url). My use-case for custom links is adding video within the gallery. Currently I have a script to take the url and wrap the image with the code used by Elementor Pro's video custom embed widget to launch a lightbox with Vimeo.
