I have a program

 http://turkos.aspodata.se/git/openhw/pdftosym/pintosym.pl

that lets you create sym/src-sch file sets.

In http://turkos.aspodata.se/git/openhw/pdftosym/examples.pintosym/
I have some examples of its use.

For hierarchical examples see 1wire_driver.* and hier.*
Another example is http://turkos.aspodata.se/git/openhw/regulator/include/

If you have a schematic containing something you want to move to a
subschematic:

. define a .pins file cont. the needed io's
. run the program
. refresh the library browser in gschem
. include the newly created .sym file
. mark the things you want moved to the subsheet
. edit-cut
. mark the newly inserted symbol
. hier-down
. in the new subsheet, do edit-paste
. connects nets to the right io-symbols/pins

Caveats:
 pintosym.pl lets you define what kind of type or label a pin has,
 see hier.pins for an example, but to do so you need to define the
 mapping

 the program was designed for mcu-kind of components, something with
 lots of pins, and if you only have a few pins, the pin placement is
 somewhat awkward

To see the program docs: pod2text pintosym.pl | less
