I am pretty sure I have seen this addressed before, but I cannot find any topics on this subject.
It is common in swing arrangements, particularly when the swing is strong, as in a shuffle) to include an indication in the tempo marking, such as the attachment below. I don’t believe this is supported directly in Dorico yet. I thought I recalled a trick where I could use musical characters from the SMUFL font to make this happen, but I don’t see these characters in the standard unicode: http://www.unicode.org/charts/PDF/U1D100.pdf
Can anybody point me to a solution that won’t require fiddling with placement on every part?
