Maybe it could be done only when in inline editing mode or in clip properties editing mode?
Also, some plugins do that... maybe you could add this feature thru the bias of a proprietary plugin like your eFX serie... or with a third party developer like with zynaptiq, Serum or Melodyne...
it would be very handy, really...
Anyway, only a suggestion to contribute to an even better DAW than Acid already is 😉
