Please give me Phantom Marks!

Hi, I moved from MC to Prem about a year ago, one feature I greatly miss is the ability to use phantom marks!  If I mark an in / out on the timeline, Phantom marks show the dynamic in / out points in the source monitor.  It's super helpful as you can jump to the in, mark it and you can easily see your out point.  I'd love to see this feature added to Prem, anyone else miss Phantom Marks?  Thanks
