That's a useful suggestion, though it can be a bit slow, and I have tried it before using the checkbox method. However, the main issue is that when working with multiple catalogs and their collections, there’s no way to identify which catalog or collection a particular photo belongs to directly from the picture itself.
I manage six catalogs, each containing around 30 collections (one of them even has over a hundred). It would be really helpful if I could view the catalog or collection information directly in the properties of each photo.
Unfortunately, this feature isn’t available at the moment.
