Enable search and filtering in subpanels

Within subpanels, users want to search and filter linked items directly where they are displayed, especially when many images or objects are connected there. This would make subpanels easier to work with, reduce the need for multiple separate fields, and simplify DAM and PIM object structures and workflows. Problem / Pain We create objects with subpanels, e.g., for digital rights management or for campaigns. Linked images are displayed in subpanels, but subpanels are not searchable, which can be a problem if many images are linked. Impact / Benefit Currently we have to use many different fields to link images to these objects so that the number of images in each subpanel is not too large. If we had search options in subpanels, we could reduce the number of fields, and the structures and workflows would be simpler. This would be useful for any kind of objects with subpanels, not only for DAM but also for PIM. Example use case A user works with an object that contains many linked items in a subpanel, such as campaign images in DAM or related product assets in PIM. Instead of manually scrolling through all linked items, the user could search or filter within the subpanel to quickly find the relevant image or object.
