Relative weapon ring timers

[Princess Plushima]

Cutting straight to the chase, is there any way to adjust the weapon ring powers to a relative value, rather than an absolute value?
IE: Using A_CustomPower could set the auto-ring variable to 20, this would be an absolute value, as doing so a second time would reset it to 20.
What I'd like is a way, other than hacking the five hardcoded things, to add or subtract values.
IE: A function to increase the auto-ring variable by 5, to 25. Or decrease it by 3, to 17.

I don't think there's a way, but maybe you can try to trick the game by putting plus or minus at the beginning, if that doesn't work, then...
