Volume Control In the BATC window#1878

Sometimes aircraft have bugs that cause volume/frequency controls to not work, despite having the option enabled for cockpit controls in BATC settings. A simple workaround for this could be adding small volume knobs onto the BATC window so that if the cockpit controls are unresponsive, you still have the ability to alter individual VHF1 & VHF2 volume without needing to turn down the master volume control in the BATC settings. This can be espically useful when you are monitoring 2 frequencies at once, and want to hear VHF1 louder then VHF2 for example.
