Q: Most efficient way to batch upload to multiple destinations (i.e. facebook, Vimeo and YouTube?)

I'd like to create a single preset that I can drag on a video to upload to multiple destinations at once; namely Facebook, Vimeo and YouTube.

If I select all three default publishing presets…

…and drag those on, this happens:

So they would all go to Facebook. No bueno. It seems that each video can only have a single destination.

I can select the video and copy/paste it two times, resulting in three videos, then drag each of the three presets onto those, to get this:

Is that the most efficient way? It's not a huge deal but I'm always looking for shortcuts.

ALSO… is there any way to save the login info for each of the networks? That happens from within Final Cut, which means it may actually be faster to just export three times from there, since at least I won't have to enter the login info every time.

cheers
