Otpion to have the time signature on-top of the staff

I would like to have an option to achieve this:

There is no manual workaround for this :

My opinion would be that it would be best manage at the style sheet level, with an option by Time Signature to follow the style, to force it above the staves or force it in the staves (same approach with Hide Empty Staves, which is managed at the style sheet level, with on option at the staff-level to force it on or the other way).

What's you thoughts about that ?

PS:
- I'm pretty sure I already saw some discussions about that, whether here on the forum or on GitHub, but I couldn't find it. Anyone aware of such a discussion ?
- the discussion is not about whether this is a good approach or not.
- I already asked on the forum to help for doing this manually, but no one manage to achieve this nicely.
