Headings font weight: set them individually?

Hi, can we set in Neve customizer different font weights for every headings?
For example, I need H1 to be 900, but H2 to be 100, then H3 to be 800 etc…
It seems there is only an option for establishing weight globally, the same for all headings…
Do you have an option somewhere to set heading weight individually?
If not, do you plan on adding such possibility in the future (eventually to choose even different font families)?
Every designer want to create maximum weight contrast between different headings…
But until then, how can it be done now using some custom CSS?
Thanks!
