Please let the user choose which microphone to use for Siri and having phone conversations.

I noticed that at some point in the past between iOS14 and iOS15,

there was a transition that made only the car microphone is chosen

for interaction with Siri and having phone conversations in CarPlay.

If there is no serious security or safety issue regarding the transition,

it would be great if you could let the user to chose which microphone

(iPhone's internal microphone or car's dashboard microphone)

they prefer for Siri and phone calls.

If it was once a standard option before iOS14.xx so it would be

as easy as adding a option switch in the Settings.
