How to combine for-each subsystems with mask parameters in Simulink

I would like to simulate an array of identical masked subsystems that are each parameterized by a structure: i.e.

clear all_params
for i = 1:5
    this_param.gain = i;
    this_param.bias = -i;
    all_params(i) = this_param;
end

Then the subsystems are parameterized with:

Is there a way to do this in a "for-each" subsystem? e.g.:

It looks like you can partition parameters, but it doesn't look like that works with structure arrays or anything not a matrix. I attached the simple model if it helps.

I figured out my problem! I was close, but when you "grow" a structure array in a loop (e.g. all_params(i) = this_param;) it populates it in the column direction. So, the example system works by either:

Specifying the "partition dimension" in the "for each" block to "2"

OR

Specifiying the structure array to be a row vector (e.g. all_params(i,1) = this_param;)
