Change macro default state

When making presets I often set the macros to .5 so that whoever uses the preset can increase or decrease it easily and it’s easy to go back to the initial state without resetting the preset but it’s somewhat annoying that double clicking the Macro sets it to 0, so I have to type it in to get the perfect .5. Would be great to be able to change the default state to make it easy to go back to the original position.
I should probably note that I’d like that only on Macros, and being able to do it on all knobs would probably cause more trouble than it’s worth.
