slides and video in same slideshow?

Kodi (ZDMC) what I will call a problem. It plays videos well, it plays picture slideshows well, but I can't find a way of having pictures and videos play together in the same show, even if they are in the same directory. I think the problem stems from the way photos and videos are setup; if you are looking at videos for example, you have to back out and enter that same folder from photos, and vice-versa. I don't know why you are forced to choose. Other players from way back just play anything in the folder, if the file type is acceptable.

Does anyone know a fix, perhaps a custom type that includes everything?
