Buttons in the centre of the Touch Bar

I can't seem to find an option to align buttons in the middle of the Touch Bar.

The size available in the Touch Bar is continuously changing throughout my day due to the media button, the call button or both simultaneously thus causing five buttons in total in the right side system buttons instead of the usual 3 I have.

Screenshot Examples:

It would be nice for an option to keep buttons always aligned in the middle.

Side question: Is it possible for there to be an option to have a button auto resize the extra padding they have inside to compensate for the changing available size of the Touch Bar.

Thank you.
