I wish that I could use a Playlist for Desktop Wallpaper Source.

The Playlist would preferably be a simple text-based list of the locations of the items, with each item on a new line, similar to the .m3u playlist format.

Not only would a Playlist give me more control over my Wallpapers, but I think DisplayFusion is my case might start up substantially faster, and with less delay. My Wallpapers are currently coming from my extensive collection of Family Photos (1000s, and many sub-folders) which I believe require several seconds of resources on startup for DisplayFusion to scan an prepare for processing.
