Adding locations in Photos App
Photos that have location data can display that location in Photos 1.0 with "Get Info". But I have not found a way to add a location to a photo that does not already have that data, nor to copy a location from one that does and paste that location onto one or more photos taken at the same spot (as I could in iPhoto).
Am I missing how to do that, or is this a feature that needs to be added in a later release of Photos? ( I see I need to update my stats. I am on Yosemite of course.)
