I can't find a setting anywhere in Options > Fonts and Colors that lets me change the font and size of the C# Interactive output window.

Here are the options:

Text Editor 
Printer and Cut/Copy 
XAML Designer 
CodeLens 
Statement Completion 
Editor Tooltip 
[All Text Tool Windows] 
Command Window 
Find Results Window 
F# Interactive 
Immediate Window 
Package Manager Console 
Output Window 
Folder Difference 
Terminal 
[Watch, Locals, and Autos Tool Windows]
Autos Window 
CallStack Window 
DataTips 
Debug Location Toolbar 
Environment 
Locals Window 
Parallel Stacks Window 
Parallel Tasks Window 
Parallel Watch Window 
PetfTips 
Task Runner Explorer
Text Visualizer 
Threads Window 
Watch Windows

I've tried customizing everything and I still can't isolate how to format this console window. (C# Interactive)

Does anyone know how I can modify this?
