Mastering one a ZOom MRS-1044 non cd non master track

[reco]

Does anyone have a Zoom mrs-1044 without the burner and its version 1 without the master track built in...........?
I am wonder if there is a way to master within the machine and not use a master recorder?
I want to be able to do a mixdown without having to use an external mixdown deck and then trasfer to the pc via the USB card that I will soon have.
HELP! Please!
