Remove or Add the object from scene sequence via script

[savaskorkmaz]

I need a solution for visualation page. Not for mosaic beta

---

Unfortunately, neither solution works for me. My goal is for the customer to change the scenarios 100% by himself, on a screen.
I have a design like the attached picture.
Theoretically, I can create a virtual output poinst and virtual selection points for all group addresses and gate them with the event script. However, we are doing this demo not for our own project, but for our dealers, and creating hundreds of additional points and creating hundreds of additional scripts is not a sustainable business and partners eventually mix up the scripts and the job becomes impossible.
For this reason, my only way is to add and remove objects with a simple script. I need your help on this matter.

Note : i can' upload picture to the post.

here is the link of screen.
