You can't.

If, however, the tvbuff you're constructing is constructed with
tvb_new_real_data() - for example, if you're decompressing or decrypting
data - you should be registering it as a "data source", so it gets a
notebook page in the Packet Bytes pane.  See, for example,
epan/dissectors/packet-icq.c for an example of code that does that.

No.
