I do not know for sure, but I have my doubts as to whether Deskscapes has that capability. You could send along a feature request to Stardock. Perhaps this feature can be added to a future version, if it is not there already. Perhaps someone from Stardock and Wincustomize can clarify and correct me if necessary. However, there are a few other options you may want to look into.

The first one is when you choose your own wallpaper and then set up Windows 10 to display a slideshow that periodically changes the wallpaper during the day and evening.

Another option is found right here:

as well as the following two options to consider.

Hope you find this post helpful and informative. Keep in mind that dynamic wallpaper apps might slow down your system in a negative way. I say "might" because I am not sure, but it may be a possibility to also take into account.

Take care
