I havent tried one myself but there are stand to pee tools for anyone with a vagina. Bear in mind that… They’re far from perfect and the way peeing with a vagina works makes it awkward and hard to use from what I’ve heard.
But no there is no way to preserve an “aimable urethra” while also getting vaginoplasty. Not unless you were still okay with having a penis, in which case there are surgical techniques that create a vaginal cavity but preserve the penis.
