Any way to get UAC to remember programs I've authorized?

Every time I want to use a certain program that I use all the time
(book-writing software; I'm a writer), I get the message that an
unidentified program wants access to my computer. I tell it to allow the
program access: that I trust the program because I know where it's from or
I've used it before.

I don't mind answering this once, for a program installed on my computer. I
wouldn't mind having to do it more than once, if I was repeatedly accessing
something on the web, rather than something installed on the computer. I
wouldn't mind having to go in and specifically designate the program as
authorized -- either in some list (like when one designates certain sites
from which one will allow popups), or as an attribute of the program.

What's driving me crazy is that there doesn't seem to be any way at all to
get Vista UAC to remember that I know this program! Does anyone know a way?
