Hi @Cokerj_99! Let me help you here.
“Set as Pivot Offset” is the usual solution for single static meshes. In order for the change to carry over in a group, apply the offset, then un-group all your elements, then re-group them again.
Alternatively, if this method does not resolve the problem, you can try manually adjusting the pivot from Modelling mode, as seen in the following guide. Hope this helps!
