Feature request: Source Timecode display for audio tracks

I have BWAV audio tracks that have embedded timecode. The Clip Attributes correctly displays the TC Start time of my audio clips. But when I move the cursor across the clip, the Start Timecode reads as 0:00:00:00 in the program window. This is not helpful. I realize that audio data is encoded in samples, not frames, but surely there could be someway to derive a frame count from an audio file given a start time and a frame rate. Would be very helpful to me!
