XCOM2 Changing Update() via UIScreenListener

[dysesothymteric]

I'm trying to change my mod to use UIScreenListener rather than overriding the class itself.

However, the part of the class I need to change is how Update() works, and thats it. (UITacticalHUD_ShotHUD for example)

 

It doesn't seem like any of OnInit, OnRecieveFocus, can do the job here. And I didn't see an eventManager hook for the update function?

Any ideas?
