Thank you for the suggestion and I will get it into the software teams.
Whilst not an easy option there is a workaround using the reference waveform feature. If you were to have both view open as you've done so in your image, create a reference of the top panel and then hide the other channels apart from the reference.
This will 'fix' the waveform in the top view whilst scrolling through the waveform buffer appears in the lower panel. Hopefully the attached video demonstrates this.
