NX having sub assemblies interact

[NX Nerd]

Hi everyone! I am currently working with an assembly in NX that I have created with several sub assemblies. I need the movement of a part in one of the subassemblies to dynamically move the other sub assemblies it is constrained to, during the movement. Currently, when I move the part, it effects parts within its sub assembly, but not in the other sub assemblies. Once I submit the movement, the effects on the other sub assemblies show up, but they don't show as I move the part. Is there a way to fix this? I have heard of 'dynamic sub assemblies' or something like it. But I am not sure where the appropriate setting is.

Thanks!
