Building a easily modifyable photogallery with CMS and Lightbox element

My client would like to be able to add new photos to the Gallery, and push them around to rearrange the order using the editor. My photos live in a CMS Collection and currently use the image field for display and the lightbox component for the gallery. However, this is cumbersome to append and modify. Using the image multi-image field breaks things down a bit but does not allow you to re-arrange the sequence of photos. One would think it would be possible to push around items in a collection list to re-order them right from the CMS page, but it’s not. Am I missing something here, or are easily modifiable and arrangeable photo galleries hard to build in Webflow?
