Make font size dependent on fallback font used

Godot Version

4.3.stable

Question

I want to use a pixel font for Latin glyphs that requires font size 16 and another pixel font for Chinese glyphs that requires font size 11. When I set the Chinese font as fallback to the Latin font its font size will be 16 as specified e.g. in the Label. Is there a way to make the font size dependent on the font used or to fix a font at a specific size overwriting any other font size values?
