Nah, probably not. But there is at least a
reasonable chance that you can change the time for the slide -
and/or - perhaps the object-time for the object to which the audio
is atttached (if not to the slide) . . .
My problem when I get in a hurry is typing "hte" instead of
"the". It appears yours might be that pesky "cna"!?
LOL! Have a good day!
