Andrew,
No, you'll have to edit one of those blocks to do that for you. There
is some work on storing serialized tags into file sinks (see
gr_tagged_file_sink), but there would need to be a similar source that
knew how to read in the tags and data and convert them properly.
The reason is that tags are sent along the scheduler as a separate
stream, so they are not treated the same as the data path
(input_buffers and output_buffers), so unless blocks that move data
into and out of a GR flowgraph know about tags, they won't deal with
them.
