I want to Auto load Lisp when Opening a certain drawing? acad2000doc.lsp?

Is there a way to make a unique lisp to automatically load depending
with template drawing I open? I have a key.lsp file that has over a
hundred little shortcut lisp that I use daily. I have it
automatically load when I open any drawing. I have added a (load
"key") line in my acad2000doc.lsp file. But when I open my
acadiso.dwt file, I would like it to automatically load a different
lisp file. How do I do that? Right now I load it manually, but I
often forget to load it, which cause me some problems. Thanks


p.s. I been told not to edit my acad2000doc file, but it has not been a
problem for me so far. So until I find a different way to load my
Key.lsp file on start up I have to continue doing it this way. I
have also been advised to use MEASUREINIT feature to switch from
English to Metric, but that does not help my situation (to hard to
explain in this post).
