Idiomatic notation for lever harp (not pedal harp)

Lever harp notation requires diamond shapes placed on the staff where the player should flip the lever to change from, for example, a C to a C#. It's done with the player's left hand. The diamond often needs to be moved manually on the staff and cannot be where a note is already being played.

I know how to change a notehead to a diamond shape but it only works on a half note which isn't normally where you'd want to place it. Any hacks or will I have to buy Dorico or Sibelius? I've attached a sample using Finale so you can see where the lever changes are and what they look like. Thanks!
