Wow hundreds at a time eh! Well my guess is that no not in 7.2 but maybe in a future version. Though it might take some work as PHP/MySQL has time-out limits for scripts to run which I'm not sure if they would apply to a file transfer that is already under way.
The whole manager for that though to me... looks like it would need an overhaul to some degree to do that many, and then also you would want more folder control, creation as sooner or later the more images you have in a folder the slower the upload and download - i.e. viewing, will be.
