There is a dead spot on the Hydraulic Lever that will help, providing there isn't a leak on the system. If there is a leak there will be no dead spot because as soon as you stop the pressure to hold it, any pressure in the system is leaking away. You need to lift an implement and switch off the Engine and see if the 3 point drops, it should take about 10 mins to drop from fully raised, but this does vary greatly depending on how much wear there is and what weight you are trying to lift, this test is with a load of 500lbs which is a 2 bottom plow. It also depends on the implement you are using, there are quite a few variables here. The reason that the hydraulics do this is because it is a Draft Controlled system and needs pressure down the Top Link from the Implement to the tractor to control the hydraulics, as opposed to a position or height controlled system that would do what you are talking about, but often there is a method to enable you to work-around the problem. Only a Draft Control is suitable for implements working in the ground. and controlling the depth. If you will email me direct at the address below and tell me exactly what you are trying to do and the implement you are using I should be able to provide you with the information you need, but do carry out the test to see if it holds first and then tell me what it happens when you try it.
