How to change location where files from channel conversations are stored

Hello,

is there a way to change the location where files (attachments) from an channel conversation are stored. Currently they all go into the root directory of that channel (i.e. /General).

This makes the root folder quite messy!

Would be nice to be able to define a separate directory: i.e. /general/conversations

BTW: A folder for email attachments is created by default as soon as a message to that channel arrived: i.e. /general/Email Messages
