>You can tie multiple toggles to the same parameter and layer, but it's too messy to be worth it
No, it's not at all messy. It's this easy . You don't even need a backwards transition. It just werks and is how it's meant to be used., as per the unity documentation. The only thing you need to do after that is set up the buttons to be toggled at param 1, 2, 3(respectively).
