Envelope Point (keyframe) editing in Audition CS6

Unless I'm missing something - there is no way to set a specific dB value to a volume envelope point? Is editing the value limited to dragging the point? If this is the case I find it near impossible to maintain accuracy, even if I zoom in sufficiently.

In Soundtrack Pro I can select a point (or multiple points), right + click - and enter a specific value in a dialog.

thx.
