This would be good to get to, also, in a global way: as Steve Parker says above “I would like these things to just appear as you write it in the popover.”
I’m sorry that Mr. Tuley has an issue with this and suggests that performers would care–much less ask for input–about a notation issue as small as whether or not there’s a period at the end of “sub.” Of course it’s entirely different than writing B#s in F major, since that’s an objective error, and this issue with the period is a preference (and besides, if that composer wishes to write B#s for some reason, they should be able to do it!)
The whole thing speaks to my general concerns about Dorico that it forces one to adhere to its notation conventions. I’m sure there are various guides to this, but ultimately one’s notation program should do what one wants it to do, and not be locked into what Durand, Faber, Garner Read, Gold, say… For all of its foibles (and it’s getting better by learning from Dorico) Sibelius offers much more freedom.
It’s fun arguing about notation, in any case, but again would be good to allow for whatever is typed in the popover to appear in the score.
