Copy Grid Timing

Maybe this has been already said.  You can copy and past blank timing, so say you split a section into 20 section and you need 10 more of the exact same timing (ex..leaping arches) you can copy a section of blank channel and past in onto the next empty section, use preserve timing and it will create the same time grid of the copied portion.  You do get a warning message that what you selected could not be copied over, but since you didn't copy anything, it doesn't mean anything.
