THere's a few ways you could for example in session view, instead of the usual ..cut, copy, paste, duplicate etc when you right click you also have 'copy automation' which brings up a drop down box that has all your automation assigned to that track.
Another way is when you copy devices like utility, filter it carries with it its automation. That's the simplest approach and I have no freaking idea why you cant do that anyway.
When you produce something like futurebass you tend to do this a lot cause your different tracks need the same pitch bends and filter cut off etc and its a pain in the ass having do it all the time + it breaks workflow up big time.
So Ableton people I hope you're readin' this.
