I have an arrangement / flow with many key signature changes (very common in scores for musical theatre), amongst which there is one section in E major / 4 sharps. In a transposed trumpet (Bb) part, Dorico would display this section in F# Major / 6 sharps. Now depending on their musical roots, some trumpet players prefer reading the enharminc spelling of Gb Major / 6 flats over reading 6 sharps including myself . Is there a simple way to have this section displayed with 6 flats, the non transposed full score remaining at 4 sharps?
Note that with 5 sharps in concert pitch, Dorico would display 5 flats in the transpsed trumpet pitch; 4 sharps in concert pitch would also display with 5 flats in a transposed Alto Saxophone (Eb) part. And: I need to specify 8 flats in concert pitch to have 6 flats in transposed trumpet pitch.
