Need help formatting the filenames of downloaded audio

[Ao1Pointblank]

using the -download-audio-as option, how can i set the file name to match this format: [target language abbreviation] - [word or phrase].mp3

it may also be helpful to other people to know how to add in the engine used, and narrator voice.

i tried figuring this out myself, and found output = text " [" Option["engine"] "] (" Option["narrator"] ").ts" on line 269 of Translate.awk https://github.com/soimort/translate-shell/blob/1e3f901c479fc4f838b290f11e1b547b86bdadd4/include/Translate.awk#L263-L275

unfortunately i'm not smart enough to figure out how to use this information myself, but i'll keep messing around.
