I have the Pioneer Receiver Remote for the VSX D1S and have a programming question

I am using my Pioneer VSX D1S remote and want to add more components instead of having 6 or 8 remotes laying around. On the manufactures code page, it shows most of my current manufactures but they do not have SAMSUNG on the list. Does anyone know how to get a code for a manufacture that was not around in 1992?
Is it possible to add that manufacture to the remote?

Thank You.
