What is the issue that prevents the Opt-D and Opt-M key commands from being assigned to Paste Special commands on the iPad like on MacOS? Is it a limitation imposed by iPadOS? If so, is this “forever”? I am using Duplicate to staff below a lot at the moment and really notice the extra gestures required to do Paste Special >> Duplicate to staff below .
e.g. 3 x Violin I; 3 x Violin II; Viola; 4 x Cello; 1 x Double Bass - all doing the same or similar rhythmic patterns you start to notice the difference between being able to Opt-D or not.
