I need to load djvu files, but since their respective pdf files have been previously loaded, the tool does not allow it.

The main reason for uploading a djvu file from the Internet Archive is that it has a better resolution and better ocr than the pdf version, this problem makes it difficult to recognize text to make transcriptions in Wikisource, in particular in Wikisource in Spanish. For example revistadelm1719101911univ was uploaded like https://commons.wikimedia.org/wiki/File:Revista_del_Museo_de_La_Plata_(IA_revistadelm1719101911univ).pdf , but i need djvu version for Wikisource, to facilitate transcription, pdf version is worse.

Also, the djvu load option should be the default.
