180-240 is a bit more than two bytes, so I'm not 100% sure that I get what you mean.
With the current approach to header words, this is not really easily supported - it's a pretty hard assumption currently that header words are at the positions (but not necessarily with the semantics) specified by the standard. This is a problem now and again (but honestly because the file is super broken), and would be addressed with a major revision of segyio.
I would like to see support for custom trace headers. EG, a 2 byte trace header in the offset region 180-240. Is this a feature that could ever be implemented in segyio?
