Trapcode Form. Create a sphere with an exact number of customized particules.

I want to create a sphere with TC Form, with an exact number of 36 customized particules (each particules representing a Football Club Logo). I managed to put all my logos in a comp, setting this comp as a texture in TC Form with with Time Sampling set on Split Clip - Loop, and the number of clips set on 36. But there is always duplicates in my sphere and some logos missing, never the exact 36 logos.

Any idea how to fix this ?

Thanks !
