FR: Some method to have a badge's initial value depend on actor data and still be changeable.

This is related to #7423 , if an effect badge is initialized with a formula, that value is not allowed to increase, and attempting to decrease it by right clicking simply removes the effect. I can understand why this is usually desired behaviour for most cases of formula badge use, but it does mean that formula badges are not the solution to the 'held breath effect' problem, ie, there is still no way to have a badge start at a certain value determined by actor data and then be ticked down per turn. I'm not sure if yet another toggle to allow for formula-set badges to be mutable is the way forward, ideally the initial value field of counter-type badges would just allow non-numeric input and become resolveable.
