Solution found I'm using the expression editor to link the values and simply add the multiply/divide by value that I want The trick is to assign everything locally, so I can use just a moving null and a driven null, and I simply multiply the local position of the moving null by a certain amount, so the driven null stay in its original position, but it will move accordingly to the axis I selected Luckily, with a bit of experimenting, I found the solution Thanks anyone for the help!
