You currently cannot but it is possible from the iOS app if that helps.
I don't use Apple, but thank you. I'm surprised that was an option they chose to cut out of this version. I really hope they do an update to correct that problem. That's kind of ridiculous.

Also, you can update Lightroom CC to 1.1 version and refer the list of feature which is added to this update.
keeps telling how to do it in Classic which I already know. I can't be the only one having this problem.
Let's just clarify, since you missed all the kerfuffle... Lightroom now has 2 versions being developed alongside each other.
Lightroom Classic is the equivalent of Lightroom 7 - it's the next one on from the version you've used for years, and has all of the features you're used to.
Lightroom CC is a brand new app for cloud-based workflows. As a version 1 app, it has a very limited featureset at this time, although it will grow over time.
So you may be better to stick with Lightroom Classic if you prefer a desktop or laptop based workflow rather than a cloud workflow, or if LRCC doesn't have all the features you need.
In short, LR CC is not a replacement for Lightroom Classic. This might help you decide which you need: Lightroom CC vs. Lightroom Classic – Which Do I Need?
The NEW Lightroom CC is a completely new program going in a new direction and is aimed at a completely different user. If you want all the features you have been accustomed to in the past you probably want to stay with Lightroom Classic CC. It is still being developed and improved and going in its direction. Lightroom CC is going to be changing and having features added over the next months and years. But only the Adobe development team knows where that is going. If you as a user expect all of the features that you have had in the past then you probably want to continue using Lightroom Classic CC. Lightroom CC is not considered to be an upgrade. Remember that! It is a completely new and different program. It doesn't have many of the features that are in Lightroom Classic CC or the older versions of Lightroom.
The new LR CC is not ready for primetime in my opinion. Also, these updates have the worst naming convention ever.
