System to allow access to backups in google drive

I am trying to add all the mods from my modpack but it is taking forever to do it by hand, I would like to propose the ability to access backups from google drive. Or an alternative would be to allow the importation of files directly from the computer. That is my suggestion. Sorry if it is more complicated than I am thinking but I feel that it would be beneficial to the players trying to import more than 100 mods

Then would it be possible to implement a drag and drop file system to just import files directly from a computer? It's nice to be able to install mods with this being an extremely reliable server host but it takes a while when the keywords for the mods aren't always the same needed for the mod to download. I don't want to ask something of you if it's not possible but this would be a really nice addition.
