watermark in plus

Can we have Watermarks in Plus? I think if you add password and e-mail to a gallery, a Watermark makes it even more safe for both clients and photographers. And it is quite east but a bit of a work around to watermark your photos anyway, since you can always export photos with watermark from lightroom and then upload those to Picflow. Now, since the LR plugin (which I love, thanks!) it would be a nice bonus to have the watermark integration in Picflow for Plus, too. Otherwise it is an option to go back to exporting and importing again, but rather make use of Picflow for fastness.
