Shuriken multiple mesh emitting?

HI!

I have made a simple explosion, which bursts out meshes at the end of the effect. The problem I am having is, that I can only assign one type of mesh. Is there any way I could assign multiple different meshes to get some more randomization for the effect?

Also the meshes are rotating the same way. Is there any setting for random rotation for each mesh particle.

Thanx in advance for the answer.
