Is it possible to add Manchu?

[crusadercrisp]

Hello! I have been translating certain manga into Manchu (language spoken in northern China, formerly official language of the Qing Dynasty) as a personal project. I was wondering if it was possible to somehow upload the completed translation onto Mangadex, but there is (understandably; it is a very obscure language) no Manchu option or "other" option.
If it is possible, please add Manchu as a language or include an "other" option, as I am not sure if anyone besides me will be uploading in Manchu. If not, is it possible for me to file my scan underneath a neighboring language (i.e. Chinese)?
Thank you for reading my suggestion!
