The benefits of tempos in lifting are unparalleled by any other form of lifting modification. Tempo lifts create balance, joint strength, and give the athlete an unparalleled benefit to slow changes of direction. Tempo presses are practically unheard of in the fitness space, but they are of so much use. Imagine an athlete who can put 90% of his best military press up in a split position, and then lower the weight for 5 seconds without changing his split position. That athlete will have a supreme amount of stability in his jerk. In addition to using tempos on your lifts you can do isometric holds with your presses. This will help build a large amount of capacity up especially in the muscles that act upon the scapula. This will also help in injury prevention for the shoulder to a certain extent.
