I was recently trying to do something similar for one of our older protocols
that nobody had yet written a dissector for, but I was unable to come up with a
solution. For me, it would have been good enough if something like "-e
data.data[n:m]" or "-e frame[n:m]" worked, but unfortunately neither of them do.
I ended up having to write a basic enough dissector to get at least some of the
data of interest out of it quickly.

I am unaware of such a feature ... but maybe I missed it too.

Yes! +1
