sorry, i assumed hand drilling.

with cnc it may be much easier the other ways.

take two steel pins (broken hss drill bit shafts or so, thin nails)
and put them in the holes (snug fit that they are straight.).
punch the same two holes through in the tt paper (drill, needle, etc).
(maybe best using far apart pins for this).

then put the paper on the pcb, the pins will align the paper.
with the tip of your iron now heat between the pins, to stick the paper to 
the pcb.

remove the pins and heat like usual.

maybe that works?
