Invert Automation feature

Please offer an option to invert automation data. For instance, on clicking Invert menu item, it should flip the values of selected data points like so:

a) turn a curve that looks like a A into an V curve.
b) turn a curve that looks like High Pass into a curve that looks like an Low Pass.
c) turn a mute automation to unmute and vice-versa

To summarize further, if a data point of volume automation is at 1.5, after invert, it should go to -1.5.
A data point of 22L pan automation should go to 22R after invert.
