Default Injecting a specific number of material Lagrangian particles

OtreborPhD is on a distinguished road
I'm trying to run a stirred tank simulation with particles that interact with the fluid and boundaries, but not with each-other.
The problem I'm finding is that when selecting the material particles model (avoids inter-particle interactions), I cannot specify a specific number of particles in my system.
Say I wanted to inject 500 particles on a presentation grid in the first time-step, and then 0 for the remainder of the simulation.
My current attempts show that the particles keep being injected every time-step (see image).

On the siemens support website they have an example of a pulsed injection (Injection every N timesteps) but I want one that is a simple on and off.

Any help is much appreciated,
