option to change default output directory

[sonycim]

Hi!

Is it possible to implement an option to change the default output directory?
Now it is /config/tts - the problem is: I'm using node red with castv2 node - if I'm trying to send the tts generated .mp3 to the device it always says no permission to that directory.
So it would be nice if I could change the tts output directory for example to the /config/www/tts which is readable by this node.

Thanks!
