roGridScreen and custom font?

[readability]

I am almost finished with my first Roku app and I am trying to make it look a bit better

I was wondering if it is possible to change the default font for GridScreen and SpringBoard or is it only possible in roImageCanvas and roScreen?
I tried to search for a way but I have yet to find an answer
thanks so much

You can’t change the font for any of the built-in screen types.
