[Mod Request(?)]

Hi I've been playing pixelmon reforged with my friend a lot lately and we decided that we'd like to play on our own server so I checked aternos since I frequent the site and tried to find the mod but it only has the outdated verson. The version we've been using (which is the latest) is pixelmon reforged 6.3.2. I was just wondering if theres anyway you guys can add it to the drop down or allow me to manually install? Thanks I appreciate everything you guys do.
