Hi, a bit late to the party here but one workaround I’ve found that’ll work until we get another update (I do believe this will be included in a future update). In setup mode, you click on the arrow next to the instrument name to open a drop menu that will display the instrument name again in a small blue box. After that, when you hover over the blue box with the name in it, another arrow appears - click this and click edit names. After this you would type in something like “Horn in F 1,2” or whatever way of writing that that suits your tastes and adjust the abbreviated version accordingly.
