Scalable dynamics

I realise that many people will have two versions of their pieces, one for playback and one for players' use. This gets over the vagaries of playback dynamics. But its not an ideal solution, requiring careful monitoring.

Instead, could a "playback volume" be attached to the property of a dynamic?
It would default to the actual dynamic, but be adjustable,

Going into the property of the dynamic, one would see for example
Displayed dynamic "f".
Playback volume "mf".

Just a suggestion. Would be awesomely useful.
