RX100 WB Set shortcut

Well, yes, you first have to set WB as an option for the Fn key. Once you do that though I think you can set custom WB via the Fn key.
I think you are getting confused between "setting " custom white balance and "selecting" the custom white balance setting. To actually set it to your exact requirements, you need to go into the menus. Once you have "set' it, you can use this newly "set" WB by selecting custom white balance from the function menu.
