Reorder elements in list nr 1 and have the changes to also be reflected in list nr 2.

Reorder elements in list nr 1 and have the changes to also be reflected in list nr 2.

I have two lists with the same order from start:

List nr 1
1
2
3

List nr 2
1
2
3

Is it possible to reorder elements in list nr 1 and have the changes also reflected in list nr 2. So the purpose is to only touch the elements in list nr 1, and have the changes automatically reflected in list nr 2.

Also list nr 2 can be reordered, but the changes would be isolated, and NOT be reflected in list nr 1.
