Customize all fonts with JSON

I am working on 100+ reports and they have 10 major categories of branding. JSON is my savior but it's not mature enough. Theme and JSON are very strong component of Power BI and it should be available.

Be great if this can be set through a theme

It would be useful to designate a font type that is to be used across all visuals.

Honestly, font settings are very awkward to use via themes. We should have access to all ttf fonts installed on our PC anywhere we select fonts in Power BI. Those fonts should then upload to PBI when we publish a report from Power BI Desktop.

This can be marked as solved: https://docs.microsoft.com/en-us/power-bi/desktop-report-themes#report-theme-json-file-format

How can I add Gill Sans MT

Definitely need support to import custom font

Can you manipulate size, font, and color of titles so they come back the same each time? I was able to do this with my legend but not my title?

Does anyone know how to import additional fonts into Power BI?

Still waiting I assume... Thanks
