Editing multiple Particle System parameters at once?

I’m using particle emitters to visualize Chaperone bounds, which is functional, but I’d like to add some animation to them via modifying a vector param.

It only works on one of the particles, I imagine the first one spawned. I think I know why, but I don’t know how to fix it, can anyone advise me?

Edit: just to clarify in case anyone thinks this should be in the VR section, the actual issue could be extrapolated to any scenario where arrays are used to spawn objects whose parameters might need to be changed afterwards, so I hope it’s general enough to post here.
