Something like this:

1. Create a program that supposed to be called by the report:

*ShowLastPage.prg
IF WEXIST("PRINT PREVIEW")
  MOUSE CLICK AT 1,25 WINDOW "PRINT PREVIEW" LEFT 
  && you may need to adjust column#
ENDIF

2. Add a field to the report and with expression
ShowlastPage()


Good Luck
