Thanks David & Jean, both approaches work well and look good. The original indications were left aligned to the note so the alignment adjustment isn't needed in this case. I have no idea if one of these is technically superior to the other, although I suspect the fact I need both sub.P and sub.PP means less code with David's approach.
I wonder if this could be added to the snippet examples about defining new dynamics? I don't think I would have stood any chance of finding either solution without your help, and I suspect I'm not the only one who might need this.
