Can we get a choice to do old-style aura?

The auras used to be circles with definite edges, but last couple of times I played/DMd it’s a fuzzy cloud instead.
Can that be a checkbox option, since I prefer the old way for visual clarity of exactly where is affected?

I also prefer a hard-edged/clearly-defined aura.

Hard edged aura is usually handier than the fuzzy one, would appreciate a toggle or reversion to the old style.
