It is possible, Adobe's PDF specification knows "Embedded Go-To Actions",
see section "8.5.3 Action Types". Unfortunately neither attachfile*,
hyperref, or xr* support this. But you can study their code (hyperref's
/GoTo or /GoToR links, file specification from attachfile) and 
write your own macros that implement the /GoToE action.
