Custom bundle identifier for a single platform

In the Config.xml, the “id” specifies the bundle identifier to use for all platforms. I was hoping to use a different bundle identifier for iOS; is there any way to specify this in the Config.xml file or will I have to resort to manually updating the platform build files after every issue of “ionic build ios” ?

I’m hoping there is a <platform …> element that can be used to specify the bundle identifier. any luck?
