Pretty sure. Although using Audiocatalyst to do it sequentially all the time is my main mode. I don't think I can be bothered doing a 'scientific analysis' of the process.
I can do additions easily by using keyboard shortcuts and mouse clicks.

1 - select music Dir in Explorer
2 - CRTL A, CTRL C
3 - ALT TAB to Emplode
4 - create playlist
5 - CTRL V
...
n - sync.

easy
