I’m afraid that’s not possible. UNIX systems don’t use the principle of volume-oriented storage, or at least, not toward the end-user.
One can split off certain directories so that their contents live on different partitions or physical drives — even on another machine across the network — but one cannot install certain applications on one volume and other applications on another, unless we’re talking of Windows applications/games, which are typically stored under the user’s home directory, but you can set up the system so that certain subdirectories of your home directory reside on a physically different volume.
