Is it possible to remove death by natural causes for agents?

The problem i have is that i find it highly annoying that the agents i took time to develop and scattered around the world will just die of natural causes.
I tried to find something related to death by natural causes, but i could only find some meaningless lookup table just saying death_by_natural_causes. Deleting it didn't help (who would really think it would anyway? :P)

So my question is : is there any way to disable the death natural cause for agents?

No unfortunately this works exactly the same as with characters as agents are just named characters. Its all hard-coded.

If you had the Alexander expansion, you probably could make all your agents have the immortal trait, that should work.
