Can't Change Apple Maps Voice?

[KooL BeAnZ]

I've always had British English - Voice 1 for my Apple Maps,

However even though this is correctly set for Siri,

There's no way I can see to change the voice of Apple Maps directions?

Anyone know if this is possible?

Currently have two different voices for both Siri and Apple Maps Car navigation.

What I've been wanting for years to do is have maps in local native language and everything else in english.. there was a brief blip last year where it looked like they were investigating this feature in betas, but it only ever did the UI not siri before it was pulled.
