I don't think there is anything to do it at the moment.  You could
probably script it from a makefile (or a bzr plugin); if doing it from
an external file you could parse the bzr revision-info output.  In
fact, bzr revision-info may be able to just update your file directly.
 Or see Ian's recent list posts about id tags in files.
