How do I define the grab point of a group of objects for emitting using coordinates?

Hi, I am emitting an object in the same scene that isn't saved out as an element.
It's actually a group of objects.
Let's say a cube and a microchip that is not attached to the cube because I am using destroyers in the chip.

I have an emitter that receives coordinates like
1,0,0
2,0,0
3,0,0
1,0,1
2,0,1 and so on.

Now unfortunately the grab point of the group is a bit random depending on how I created the group and objects.
How can I define which point in the group is the grab point that will then end up on these coordinates?

I also noticed that when I modify objects in the group while the emitter menu is open I can see the changes reflected in the preview. But if I assign that object again to the emitter it will jump to a new position.

Showing grab point only works for the whole scene rather than the group I scoped into.

What are the usual techniques to stay "clean"?

  Is the emitter just calculating the center point of the bounding box at time of object selection?
  
  I just don't want to feed in more values into the emitter coordinates than needed.
  
  Modifying the grab point of the group would be nice or moving the preview like you can do when the emitters coordinates aren't wired.

  When you say "grab point" do you mean the centre of the emit object? Yeah you got it spot on. We can't define it directly.
  
  I've got a tutorial here that shows methods of setting the centre pretty easily: https://www.youtube.com/watch?v=PrSvthGCouI&list=PLX3qX-yI9vm4Dem2z3XV8LTb3M4NQdM6D
