Forgive me if i am wrong as i have never really used the bulk edit tools that much. But it would be great if you had the ability to bulk edit all your videos but leave your description the same. For instance you might have updated your channel defaults ( so in your channel description section you might have a load of links you want in every video) but you do not want the video description part to change. So almost if there was the ability to split the description box part in to fields as such leaving the top part (your video description the same) and the rest you would be affected by the bulk edit. I hope that makes sense!
