Edit by source timecode?

I have some broadcast WAVs with timecode. I want to patch one little thing in my mix which is sync sound to video. I know the timecode of the source in relation to where it is on the timeline… but I cannot for the life of me figure out how I can see the source timecode of the file in the sample editor, in order to mark the chunk I need and drop it in. It’s always showing me the start of the audio file as being that of the start of my project.

I’ve been buzzing through the manual and cannot find any mention of anything relevant. Can I seriously not see source timecode (besides the origin time in the audio pool)??
