Tag request: interlaced vs. progressive video

I'd like to have a tag that's similar to <Video Height>, but has 'i' (for interlaced) and 'p' (for progressive) appended. This would be helpful to indicate if the video was encoded as 1080p or 1080i, for example.
Reply to #1:
You can use the tag <ExifTool=VideoScanType>. You will get Progressive or Interlaced, then you can replace for p or i.
