As of right now (v2.31) when saving multiple .torrent files, if some torrents have the same name, only 1 will be exported, can this be changed? Perhaps attach the hash to the .torrent file name if duplicates are found?

This is appended by the (1) (2) behavior pre-fixing the existing transfer name I think.
This is because if you try to keep the same name, Tixati will try to merge, which in some cases is fruitless, different sized files (nefarious file is too big error)
