Suggestion:Add a modify to audio set default

[Selur]

Send you a link to a dev version, which should allow to set 'default' to 'true' if 'Base->Processing->Audio' is set to 'custom'.
So you could:

• set 'Base->Processing->Audio' for example to 'passthrough (all)', to populate the list when loading your files
  
• load your files
  
• change 'Base->Processing->Audio' to 'custom'
  
• switch to the 'Audio'-tab, right-click on the entries you want to change to 'default' 'true' and select 'set default'.
