Set MP4 as the Default Output Format?

[wfz]

Hello
I usually use MP4 as my only output format. The default is MKV and I have to change it to MP4 every time I use the program. Is there a way to Set MP4 as the Default Output Format? Besides the interface, I checked some text/XML files, but couldn't find anything related to the output format.

Thanks,

You can save it using Edit/Save current settings as default.
You can recall it via the Ctrl+R shortcut.
