[Cascade particle] Emitter Initial Location

I am using the Emitter Initial Location module to create a trail of particles emitted from a spawning emitter.

My problem is this way the distribution of the sub particles is divided between spawning particles, furthermore, the distribution is uneven as some spawning particles have died and new particles are born, no matter how high the spawning rate I boost.

Is there any way to change the spawning behavior per individual spawning particle? Also is there anyway to order the sub emitter not to emit any particle when no spawning particle present?
