Duplicating Effects

I have a selected object with multiple stroke listings of various colors and weights in the Appearance palette (Window > Appearance). The top-listed stroke in the stacking order has a Roughen Effect (Effect > Distort & Transform > Roughen) applied to it. The effect is included in the listing under the top stroke. Is there a quick way to duplicate this effect for other stroke listings?

Yes! Click on the effect listing and Option-drag (Alt-drag on PC) it over the top of any other stroke listing in the Appearance palette, and when the listing is highlighted with black arrows on either side, release your mouse and drop the effect onto that listing.
