Passthrough default, Emulated Wiimote per game, possible in ini?

[e2zippo]

So I'm wondering if it's possible to have Bluetooth Passthrough as default, and in the game ini change to emulated wiimote.
For instance, I don't want to use the real Classic Controller for Super Mario 64, I want to use my WiiU Pro Controller instead.

I tried to add WiimoteSource0 = 2 to the ini where 2 is supposed to be "real wiimote" but I guess that's before Passthrough was introduced.

Is it possible to change this?
