Thanks Weston for the link. That solved the problem for plotmaker templates (pity you can only have one file though).
But does anyone have a solution for the BOOKNAME problem. I know that with V8.1R2 you can specify weather or not the drawing name has an extension but it would be great if you could do the same with the bookname. So that if we name our layout books in accordance with the projects stage (eg Preliminary Construction Issue) then that can be incorporated into our master layouts.
