Create duplicate versions of the fingering articulations.
Edit the duplicates so that they have different vertical positions.
Assign metatools to the fingerings for fast entry.
If you need four different vertical positions (four fingering numbers above each other), assign metatools so that the letter Z key positions a finger number '1' at the lowest position, the letter A key positions a finger number '1' at a position 24 EVPUs (= 6 Points = 1 Space) higher (or whatever amount you want), the letter Q key positions a finger number '1' at a position 48 EVPUs higher, and the number 1 key positions a finger number '1' at a position 72 EVPUs higher.
Similarly, assign metatools so that the four different position of a finger number '2' are programmed to the keys X, S, W, and 2.
Similarly, assign metatools so that the four different position of a finger number '3' are programmed to the keys C, D, E, and 3.
B) Encircled numbers:
1. There are fonts with "number-inside-a-circle" characters, e. g.
You can attach a such "number-inside-a-circle" character as an articulation or as an expression.
2. You can also create the number as a text expression, and give the text expression a circular enclosure.
3. And you can create the "number-inside-a-circle" in the Shape Designer, and use it as shape expression or as shape articulation.
