Microphone Input selection

Hello it would be nice to get back the function of being able at least by activating siri to have te option to select the mic source.

This function was available on a earlier ios by tapping on a miniature Bluetooth symbol that appeared somewhere on the top right portion of the screen when siri was activated by long pressing the home button “this on earlier iPhone”

My particular problem is a bluetooth speaker that has not got a microphone and if dictating a text or sending a voice message is not possible as there’s no audio input, so you send empty voice messages.

It would be wonderful if this could be settable in the bluetooth settings, allowing the changes to be permanent for that device. When choosing a audio input was possible on earlier ios’s this preference would of been valid for the duration of the bluetooth connection period, so when connecting again this had to be changed again.

Cheers ;)
