Import Custom Linetypes into DWG File

I know that I can import custom “linetypes” into my current DWG file by importing my template file from the import linetypes button.

What I would like to do is import just one linetype style, into any current DWG file (i’ll add it as a script to a button).

How do I export a LIN file from R8?

Ah sorry John, thanks.
