M4A filetype allowed / Configuration Override

[dot.net]

Is there a way to specify that .M4A files (mpeg4 audio / QuickTime) are an extension that can be launched from the Files list? I took a look through the .nbi/.xml files in my data directory and nothing seems obvious. Or, must this explicitly be added to a whitelist of allowed applications and built into newsbin? I'm running 6.10 / Build 1337 / 64-bit.

Thanks.

It's built in and I just added "m4a" for you.
