Use several custom fonts

I would like to use several custom fonts (Roboto Regular, Roboto Thin, Roboto Medium, and Roboto Bold) in a Power BI report. Ideally I would like to be able to select any of the mentioned fonts for both text boxes and text in visual elements such as matrices, plots, etc. 

I have succesfully added the Roboto Regular font to Power BI using the following code in the Theme json file: 

{"name":"Custom fonts",
"visualStyles":{"*":{"*":{"*":[{"fontSize":12,"fontFamily":"Roboto","color":{"solid":{}}}]}}}}

However, I am currently unable to use the Roboto Thin and Roboto Medium font while also maintaining the Roboto Regular font as an option. 

This question (https://community.powerbi.com/t5/Developer/How-to-import-customized-fonts-Regular-Bold-Semibold-light-etc/m-p/1051904)  from 2020 suggests it wasn't possible before, but as there have been changes to the fonts in Power BI since, I would like to hear if there is a solution now in 2022?
