Can't be done, but since you can see both spaces at once it doesn't matter
that much IMHO.
If your protocol involves many layers, as mine does, you need to come up
with easy ways of dealing with the density of information. I use logical
prefixes in my layer convention that allows logical groups to be killed in
one swoop with wildcards. This can then be put into a button, the buttons
grouped into flyouts, etc. I also have a nifty command-line version of LMAN
that Allan Seidel developed that saves the current layer setup and can
recall it without using the clunky dialogue. This can also be put in a
button, and grouped into flyouts.....
Anyway the point is that you have to get expert at manipulating layers if
you're going to have lots of them. Using a dialogue and picking them would
question* for me.
LISP can be invoked to help you out here too. There's at least one, VPFRZ,
on my site you should check out. It's a point-and-shoot version of VPLAYER.
There are lots of lisp routines for layer management available elsewhere on
the web too.
