Would  SDR Console's Data Analyser do what you're suggesting?  

Carrier Sleuth ( https://www.blackcatsystems.com/software/medium_wave_carrier_display_app.html )  can also display carrier shifts and smearing due to propagation changes.

That brings to mind a possibly interesting feature for people into observing changes in propagation would be a means of creating VERY slow waterfall images, once a second, once in 10 seconds, once a minute, once in ten minutes, etc, probably in a traditional 1,2,5,10 sequence. Then you watch the pips move and change with time. With a fine enough spectrum plot you can possibly actually see the frequency changes as the ionosphere moves up and down and the D layer comes in and out. It could be used for education. {^_^}
