Roke: The Dark Lord

I've looked around and appears i have a problem. I can't seem to find a way to Install the launcher to a different drive. If my fears are correct and It is indeed not possible i'd like to suggest it as a feature for the new launcher. For those like me who have most their game data seperated from the C drive. Frankly i don't have enough space on my C Drive to house all the mods i want. sorry if this is the wrong place to put this. Wasn't sure were to find a suggestions box lol
