How to change some global parameter inside graph?

I want to have some global param and change it every tick. For example I want to keep global emitter position and change it applying some small transform every frame.

I tried to use custom attrubute but it seems that every particle have it's own instance of that attribute. Am I right in this assumption? Is there some way to have global atribute and change it inside vfx graph or I should use c# for that?

 

Very curious about this also!

 

Same here. Is there any way to setup some Global parameters in VFX Graph ?
Maybe there is an option to do this similar to Shaders.
