How do I set more than one background for the lock screen?

[Android Central Question]

I used to be able to set 30 pictures for the background for my lock screen, now that I've updated my phone, I can only set one. Anyone know if they removed the feature?

Can't find it on galaxy S8 running 8.0 with experience 9.0 either. Though slideshow is available in the settings.
