Curved vol. envelope for VST track

With audio track we have full control of envelope. I wonder if i can have these tools on the VST instrument’s audio channel? I want to create curved volume envelope and do some experiment. “Drawing” i am not happy by the way. I know i can always export to audio then play around but i am on the action, need to change frequently. I can’t keep export and try that one, this one etc…

Any help?
