How to set a particle emitter's location box size via variable?


I’d like to create a particle system that emits particles within a box. The first thing I did was to add a “Initial Location” module to the system and I typed in “100” for the max values and “-100” for the min valuies. the result is a particle emitter that emits particles within a box.

Now I want to reuse the same emitter for different effects and they require different box sizes. Setting the box’s size via variables on emitter spawn would be the ideal soultion. Unfortunately I can’t do this because if I set the distribution to “Distribution Vector Particle Parameter” the box will be replaced by a singular location that emits the particles. So the only thing I can do is offset the location instead of adjusting the box size.

Is this even possible in cascade?

Thanks and best regards,
