Can someone from Adobe let us know if this is planned for a release soon?
Since we are not Adobe here in this forum (we are just Lightroom users), we can't help you. Furthermore, Adobe themselves almost never pre-announces feature enhancements, you'll just have to be patient and you will learn at the exact same time everyone else learns of new features.
Or you can sumbit a feature request, the link for this is on the first page of this forum.
Like DJ-Paige says, we can't speak on future release features, but what I'd suggest for this feature that isn't there now, to post a feature request "idea" post over on feedback.photoshop.com/photoshop_family.
If you post on that site, others can vote up your post which helps us gauge the need for this type of feature. If others want this as much as you, pass your link on to them for voting it up.
Thanks for your feedback on LRMobile, and your workflow needs.
Hope this helps.
Thanks Pete - I appreciate the pointer.
I've added my vote to two very similar feature requests - I hope Adobe take the two requests together to get an accurate view of the strength of feeling.
