A way to tell which vertices are affected by "hook to new object" command.

When using "hook to new object" why doesn't it create a vertex group or something so you can tell exactly which vertices are associated with the hook modifier?

I had been manually setting up the hook modifier and it wouldn't do what I needed unless I gave it a vertex group.

Using ctrl+h > hook to new object does exactly what I needed but it does not create a vertex group yet somehow it works fine.

I used hook to new object on the eyes of the monkey but there's also one vert from the cheek that was included. There's no vertex group so I can't just remove that one vert. I have to create the hook all over again.

One of these works and the other one doesn't and there's no way to tell them apart: i.imgur.com/LFHfxJe.png

The one that does not work would work if I chose the vertex group I created for the eyeball verts. The one that works just magically works and gives no indication in the UI of how it knows to only apply to the eyeball verts.
