When I am going through a batch of photos and adding descriptive tags, I have only found I can add one tag at a time.  Is there a way to choose several tags at one time to add to a photo.  Example:  I want to add these tags:  Josephs Birthday, Decorations, Cake.  Is there a way to pick all three at once instead of individually, which is very time consuming.   I guess it could be called Batch tagging.  Thanks
