For skeletal meahes, Unless they removed or broke them you should really just be using ragdoll profiles and swapping between the predefinitions you make rather than setting things as a one off via code.
It’s not only best practice, its going to save you from feeling like an id1ot when you can’t figure out why x joint is stiffer than Y after a day of looking at it due to some lost code function that you called in a forgotten one off…
For the other stuff you are kind of stuck to the code, but you can centralize it the same way.
Create a c++ component class, make the function avaliable within the class. Attach the component you created to the object you want to control, then call the component’s function.
Its still a one off, but you can search references to the class to hopefully find the issue on the fly.
