If it is set to go into the same channel it replaces, if a different channel you will see them both on the list. You can only inject into a channel that already exists. ChanVis tells Poser to show the dial or not, I gather Poser 5 doesn't support it, though, as all show anyway. P4 and PP do suppot it, BTW. "Deltas" are the actual morph information, it is only 1 line in CR2 Editor, but many lines in the real file. You only need delta information when you are putting it in. ;-)
