If you mean that you are going to another layout and returning and you want it to be there in the same place it was before, you can use something called Persist behaviour.
If you mean staying in the same position and appearing in the next new layout you can give the object global properties, tick global on its settings, and it will remain in the same place and follow through to the next layout.
What previous person is proposing is that you can store the co-ordinates of the object in an array or a variable and use these later to set the objects position but you will also need to create the object again when changing layout.
