Mid-measure clef change
I don't know if I should file this under Support or Feature request. I've not found a way to do it.
Some scores I occasionally work with are best notated with a clef change mid-measure. It's fairly common, for example, in scores for viola, where the change is between the C (viola/alto) and G (treble) clef.
All my attempts to date to do this have failed. The clef change is forced to the beginning of the measure (or end of the preceding measure). If there's a way to do it I'd like to know what it is. If not, I suggest it as a feature request.
