Yes, you can draw one in the symbol editor.  The easiest thing to do
is to get a source out of the spice directory which is close to what
you want, then do right mouse->down symbol, and then redraw the symbol
to your liking usign the graphical elements available in the toolbar.
Do edit->toggle attribute visibility and then give your dependent
source a DEVICE attribute which will be recognized by spice-sdb. When
you are done modifying the symbol, save it out under a new name.

The process of creating symbols is documented in the docs distributed
with gEDA/gaf.  Alternately, you can just do what I outline above, and
with a little playing around, you will have learned the symbol
editor.  It is quite easy.

Have fun!
