I've been lazy/busy about doing this when I realised that it required
a new implementation in C++.

I would be happy to add those options, if someone else codes them. Do
you want to try? I think it's a fairly simple task for C++. It should
even require less trickery than any m-script implementation. If you
write the initial implementation, I can polish it later (not sure how
confident you are with C++) and then push the changes to the repo.
