O.K., back to basics- you can create a magnet from any part, and go in the magnets properties and have it effect other parts, but it will start out with the zone centered on the part. With the Posette it is different, but Vickie is arranged so the body is sliced up in the chest area into a narrow strip down the center called the "chest" part, and a part on each side called the "right collar" and "left collar". An "Implant" morph is going to primarly push out the breast area (which is in the "collar" part, but it will also have to work a little on the "chest" part (we are talking Pam Anderson size morphs here). So, you would create the magnet from each collar, but each magnet would have its porperty set to include the chest to, and once the magnets did their work (by the correct setting) you would spawn a morph for each of the 3 parts. The above assumes you are going to make the part morphs by magnets, you could also make them in your favorite modeling program, but you would still need 3 of them, and it would still be a good set to create a full body morph for.
