Envelope curve suggestion

Would it be possible to enhance the current envelopes so that each stage of an envelope can individually be morphed continuously from logarithmic through linear to exponential? That would allow for much more flexible and detailed modulation options.
It's not really possible to do that, I suggest you use a few envelope points to approximate the needed shape (usually using only 1 intermediate point in linear mode is enough to sound like exponential or logarithmic).
