You can make soundpacks of your own sounds (already in your soundlibrary) by going into the soundlibrary (main msn screen, Plus icon), then choose "add new sounds" and "export existing sounds to create a new soundpack" (rest is selfexplanatory). After doing that move that sounpack to another computer and import the soundpack (soundlibrary > add sounds > import sounds from an existing soundpack...and browse to where you stored it).

You can't browse all sounds because the feature isn't set up/ment that way.
