Bulk "lifting" pauses to other track instead of deleting them

I would love to be able to move all "silent" areas of my video (meaning parts where I am not talking) to another track - because I usually do not want to delete them but speed them all up, as I am doing a lot of instructional videos. This would be a real game changer for me. And as it is already possible to delete all "pauses" (lift) I assume it must be quite simple for you to pull these areas to another track. I think this would be really usefull for all who do instructional videos and in general to be able to see and here what would be cut away.
