Set stroke width to SVG font

I would like to export SVG font directly from the App. I can set the fill colour, but can’t set stroke-width or ending cap. Please, is this possible or do I have to create the SVG’s outside of the app and import them? Other option would be to add the stroke width after the font’s export with fontTools, but it would be nice to keep everything in the source file.

Thanks, Jan

That is currently not possible.
