Yes, this is possible. There is a subcarrier mask concept in the
modulator and demodulator block that you should be able to use. Right
now, it specifies if a carrier is in use or not (e.g., data or
nothing). There are some hooks in there to add pilot tones pretty
easily to the modulator. Actually using them in the demodulator is
where you'll have to focus most of your attention.
