[Feature Request] Abillity to change metadata for author on batch conversion.

[Treishpel]

Right now it seems like all converted files have the metadata for the author set to KCC, so in order to get proper author metadata I upload the file into Calibre, change the metadata around and then I have to resave the file locally and upload to the device.
Using the send to device feature from Calibre seems to still do the KCC author even though it was changed inside Calibre.

It would be a cool QOL feature to be able to set the metadata for author before conversion. Maybe a text dialog or a textbox added somewhere where we can set what the author metadata should be set to after conversion, so if I'm converting a whole series I can just set the author of the series, convert and with the new PDOC change it should be possible to just transfer the file straight to the device.
