Adding connector to circuitworks library

I imported a PCB that was done in Cadence and I used the emn file. The board came in to solidworks OK but all the components are blocks. I would like to add the main connectors used on the board that I imported from tyco website instead of the blocks. Can anyone please tell me how I can add these components to the library so when I import the board it will refer to these components instead of blocks.

I tried the help but I am more confused after I read what is in there.

Kris.
