Request method to specify that key signature being added is already transposed
When creating or changing the key signature of a Baritone Saxophone, the key signature is not the one I selected.
Steps to reproduce :
1. Create a new score with a Baritone saxohpone
2. Select D major for the key
3. Click finish.
4. The key shown in the score is B major.
If I switch to Concert pitch, the key is the one I chose. So there's a bug between the two pitch mode when setting a key signature to an instrument. Same happens when drag-dropping a different key sig.
