I have expressed myself probably in wrong way.

There will be a struct called "via".
It will contain a "hole" and pointers to attached object on
all affected layers.

So when you click on the "hole" you can change parameters of all
attached object at once. When you click on the attached object on some
layer, you will change just that object. So moving will be possible just
by moving the "hole".

This can be easily programed, as when clicking on hole, you will have an
array or something of pointer to all object, which you want to change.
On the other way, the object lives on some layer, so you can treat it
as any other object.
