How can i replace lowres path with Highres path on export

Hi, i have a problem with `attaching` highres path with lowres path on "Export"

Points to be noted:

1. i have lowres path and highres path in my drive. i,e /highres, /lowres (both of them having same filename & extension)
2. i do editing on lowres files once editing is done, i need to apply editing on Highres files
   

here is my export code:

var outputDirPath = 'F:\editing\final';

varjobID = app.encoder.encodeSequence( app.project.activeSequence,

                                        outputDirPath,

                                        outPreset.fsName,

                                        app.encoder.ENCODE_WORKAREA,

                                       1);

Question:  how can i replace "lowres files" with "highres file" on export (Note: i don't want to use "Default" Adobe proxy attching, i have already generated proxies which is used by other apps, so i want to use that ).
