Depending on what your looking to accomplish, http://geck.gamesas.com/index.php/gamesas_Tutorial_Static_Collections may be the right solution. With SCOLing your taking a number of existing statics and combining them into a single new static, like glueing a bunch of legos together. You can multi-select the statics you want to join and press Control-G then Yes to join them into a new object.
There is no other known batch process for creating individual NIF files from scratch using the GECK other than SCOLing. If your simply looking to add new objects to the game, those have to be done one at a time.
Luck,
