Requesting Desynthesis

The game has a request meld option so I figured:"Why not include a request desynthesis option?" I know it might incite people to be significantly more greed driven, but the truth is that people remain ever so greedy. Right now, lots of people still have primal weapons that are wasting away. I've seen people choose carpenter, alchemist and culinarian and now they have no hope for get mastercraft demimateria with any consistent frequency. People might be against it, but I personally think it's a great idea. While we're at it, it would also be nice if people could request repairs from party members.
