I essentially use Notation Composer for transcribing classical music from sometime quite old sheet music and in the baroque period some ornaments are not always written in the same way as in Notation.
The major difference is the starting note: for example, a eighth note C with a trill will be played D, C, D, C.

Would it be possible to have an option for starting an ornament on the upper note? So far I have been obliged to enter the notes "as played" which far from ideal.
