For the playback, use hidden notes in another layer (e. g. a hidden layer).

For the layout notes, de-select playback, e. g. via the very technical Speedy Entry Tool dialog box Edit Frame (exit the Speedy Entry rectangle, hold down alt, and click the measure/staff).

One can tie two C#'s together and then via Speedy Entry change the second C# to Db by choosing the note and using the "9" shortcut. The tie will hold.

If I understand the problem correctly, Thomas Kim is asking for a solution with both correct playback and layout.

Are you saying that your solution gives correct tie playback (= only one, long tone)?

I can not make that happen; I get two whole notes in playback.

True, the notes repeat; that is something a future version Finale ought to correct.

The OP might also consider entering just the layer 2 notes in the measure(s) in question in a non-playing layer (I use layer 4, muted) and then adding a playing version of the second layer notes in a separate staff which can then be hidden. It is arcane, to say the least, but as you say, the Speedy Entry Frame is very technical.

Kind of a "pick your poison" situation.
