Select several pictures and move them in one go?

Am I correct in understanding that Google Photos is unable to let users 1) select a bunch of pictures (such as through the check mark + CTRL key), and move them all in one go?

It looks like you can only move one picture at a time. Besides, Google Photos is pretty slow.

I tried Picasa, but for some reason, the sort order doesn't match what I see in Google Photos.

Thank you.
