Manual volume controls in iOS camera app

I already put in a bug report suggestion on this issue. I love the interface of the iPhone's Builtin camera App. But I use External mics. I want to be able to adjust the Left/ Right channels for my mic. I have a Sermonic 2 channel XDR Amp made for the iPhone. Yes I could use Filmic pro and that works OK. I have used it but I take a lot of Photos and videos when going to Classic car events and I switch back and forth between taking videos and taking Photos. Apple has made the builtin camera app very easy for performing this function. All I need is the addition of a Mic Volume control.

Also In the Photo mode I would love the addition of taking 4k/60 video. I think right now you can take only 1080P video in the photo mode. And you have to switch to Video mode in order to take 4K/60 and ProRES video. I realize the video recording feature in the Camera photo mode is meant just for taking short small videos so why would you want to take video in 4K. 1080p saves space. But the design of the mode/function is so nice that I would like a setting to take 4K/60. I bought the iPhone 14 Pro Max 1TB so I could take all video in 4K dolby vision all the time.
