Add ISPP's {#CompilerPath} and {#SourcePath} to autocomplete. Would like to add {#__FILENAME__}, {#__PATHFILENAME__} and {#__DIR__} as well, but not with those names: too ugly + wouldnt be grouped together + not clear enough that they only apply to include files. So should think of new names before adding them.
