I can't answer your question directly, but:-
I guess you are talking about the schematic part (.lib). For the pcb part (.mod) just use the generic foot print.
It actually doesn't take long to make a part.
Open up the schematic library editor.
Select a working library, make a new part then just keep adding pins.
On each pin you just specify Name, Orientation, and how it is used: GPIO use bidirectional ;Vcc, Gnd use Power in;
I use a split screen on my monitor half with Kicad, half with the datasheet.
If you want you can adjust the symbols, maybe use different ones for power.
Organise them neatly either sequentially or by function.
Then draw a rectangle around them.
If you want you can add some metadata by clicking properties. If in doubt look at another part with the library editor.
Done.
ps. I thing I find very useful is to put all my .lib and .mod files, as well as design files, into source control. I use TortoiseSVN. It just covers you if you make a mistake.
