Expression Maps

I have created my own expression maps and playing techniques for several of the EWSL Silk sound library instruments. I figured out how to “Export Library” for the expression maps (by selecting all of the maps and pressing the “Export Library” button). But I can’t figure out how to save/export the playing techniques I have created. Of course I need the notation that triggers the playing techniques to be exported and imported to any new scores. Please advise how to do this. I notice a “Save as Default” button at the bottom of any single playing technique that I edit, but I don’t know what that will do. Thanks. John O
