how to have a script reference to sub products ?

To simplify my scenario, I need to have references of multiple subproducts (8 products) into a script that will be in charge to show/hide all (or a part) of this references with one function I called into scenario.

Currently I need to add 8 sentences into scenario to make the same thing ... particularly time-consuming and bad visibility on scenario, because in my case I need to do this 6 times in scenario. If references changes, I need to edit 6*8 sentence in my scenario.

My problem is, except in scenario editor, I don't found a way to have this references in my script ...
- I try to add in a collection, but subproduct don't list any of my collections when I do right-click on subproduct>Collections>add to..
- I try to list all actors of scene by script but my sub products don't appears
- I try to add it has property in my script but subproducts don't appear in 3D Actors list
