In the future I could vision this work quite well using dedicated tracks for automation envelopes.
Together with pattern zooming (that also implicate delays for fx’s) you could optionally show the automation data as dedicated pattern editor tracks. You then see the automation data (points) as numbers in the pattern editor. So by moving these you are actually moving the data in the automation.
Another concept we could use in addition to dedicated tracks is to give each note more properties like explained in this thread. There you see special data connected to the note it self. So when you move/delay a note you also move/delay the fx-data connected to it.
