I remember reading about this somewhere (sorry, I forgot where...). Someone used a script to accomplish this. I forgot how it works though... =(
Anyways, the way I think about it is:
Create a script that jumps to the end of the current track. Then, assign this script to a keyboard shortcut (I think assigning shortcuts is possible). So next time instead of pressing the next track keyboard shortcut, press the shortcut for the script.
I have no idea how to write a script, but that's the idea I came up with.
Hope that helps at least a little!
