pEmitter with multiple sprite bitmap

Hi,
For now i had to use multiple pEmitter if i want different sprites, kind of unproductive...
What is the right way to do that ?
In particular we have toons of option to do that, In nuke you just input multiples bitmaps

PS: In the doc they literally skip the style type, where can i get more info about that ?

Thanks
