Save the output of Tag Debug to CVS file

Dears, 

I am working on GNURadio flowgraph where I use a Tag Debug block (https://wiki.gnuradio.org/index.php/Tag_Debug). 
In my grc-graph, the output of Tag debug is displayed on the command window as (I,Q) tuples.
Can I save the output of the Tag debug displayed on the command into a cvs file?

Thanks,
HZ
