If you want strict control over the file-size, then you'll likely need
to write your own block.
It should perhaps NOT come as a surprise that there aren't examples that
cover every possible use case, since the field-of-endeavor is
essentially-infinite, and there's only a finite number of entities
working on this stuff....
The www.gnuradio.org [1] website has lots of tutorials, and info on
writing your own blocks...
