Familiar shared spell question

If you cast a shared on you and your familiar, can you cancel the spell on only your self? Thanks

As far as I can tell, dismissing a spell is an all-or-nothing proposition - you either end it for all subjects or keep it going.
Note that you can cast spells with a range of 'personal' on your familiar as though the range was 'touch', which might allow you to achieve the same result.

There are ways to do it with some spells, in some situations. But it isn't by canceling the spell.

Cast invisibility on you and your familiar. Make an attack. Now the invisibility on you is gone, but your familiar should still be invisible.

But you can't simply cancel it on yourself. You need to find some other way to end it.
