Regarding "Timed" layers

Hey there!

On a certain slide, I have many layers.

The first several of these layers are advanced

by the user "clicking" on a certain part of the slide.

Now here's the tricky part.

On this same slide, I want to start a "timed"

presentation that begins right after one layer in

which the user "clicks to advance."

I understand how to set this up on the "base layer." But there

seems to be no option for me to change a "later layer" into a

"auto-advance timed" layer.

The "properties" given for later slide "layers" (beyond the base layer)

does not include the option to switch to auto-timed advance.

Any solutions?

Thanks in advance for the help!
