LibGDX - Dynamically change particle emitter's Atlas Region?

Is it possible to dynamically change the Atlas Region used by a particle emitter?

I've tried...

effect.getEmitters().get(0).setImagePath("[someAtlasRegionName]");

...but it continues to use the original region the effect was loaded with.

There appears to be a .setSprite(Sprite) method but it doesn't work with TextureAtlas.

Thanks.

Editing the Sprite's fields to set it to the TextureRegion works (Sprite extends TextureRegion, so it has all the relevant fields):

Sprite s = effect.getEmitters().get(0).getSprite();
s.setTexture(vessel.getTexture());
s.setU (someAtlasRegion.getU());
s.setU2(someAtlasRegion.getU2());
s.setV (someAtlasRegion.getV());
s.setV2(someAtlasRegion.getV2());
effect.getEmitters.get(0).setImagePath(someRegionName);

Edit: I don't know if ParticleEmitter.setImagePath() matters or not, but I'd include that as well just in case - it definitely won't hurt. So I added that as well.
