If you try to send a non-device-supported file to your ereader, calibre helpfully offers to convert it. However, I can't seem to figure out how to select specific "autoconvert settings"; neither the granular stuff like whether to add a TOC or smarten punctuation nor even the most basic stuff... like what format I want it converted into. For Kindles it seem to automatically select MOBI as the output, but I'd much prefer azw3... and have the same kind of control over conversion preferences that are afforded by a conversion that's saved to one's computer. Can anyone tell me how to do this?
