You would have to unpack them using FOMM, but instead, just look at all the notes, and right click and select 'priview' until you find one that looks like a Holotape or paper or whatever. Then open that, edit it to what yours says, then click ok, when prompted to make a new form say YES!!! if you say no it edits the actual item ingame. If you say yes, it keeps the original and also creates your form. This is much faster than extracting the necissary files and directing it to that nif.
