Subtitle text center alignment for Android

[markedby]

Issue Description

There is navBarTitleTextCentered property for Android which works great. But the same alignment property for subtitle is currently missing.
I'm desperately need to be able to center navbar's subtitle on Android. Is there any possibility to implement this?

I am also facing this problem. It would be cool to have something like "navBarSubTitleTextCentered" navbar's prop on Android.
