Release time scaler

If this has been requested yet... sorry ;)
When busking shows i‘d love to see kind of release time scaler.
I have bump intensities on my faders/buttons. I‘d like to have the possibility to scale it’s release times so that i can adjust during songs. Fast song -> fast releases....slow songs->gentle releases.
Therefor u safe faders/button to achieve different behaviors.
Can’t remember if any console i used can do this.
Would be a cool feature.
