It may be that is should not be separate in the first place. I gave you
an example of when this would be poor design. It is easy to think of
plenty of other cases where not having a separate circuit makes more sense.

It all depends on what the circuit extension is for. Since you don't
know, it is better to stop guessing.

Neat and easy and not
ramming too many cables into one terminal.

You have never wired a modern CU have you? Get real.
