Can I tell Visual Studio that a certain file extension is a C++ module interface?

Question

I have been working on a C++ project with clang. For modules, their documentation recommended file extensions like the traditional C++ extensions, but with an "m" attached. So: .cppm, or .ccm, etc. Since I had been using .cc, I started using .ccm.

Now I've moved to Visual Studio, and it wants to see .ixx for primary and partition interface files. I see I can go to a file's properties and manually set its "Item Type" and then "Compile As", which lets me force it to treat anything as a module interface file, regardless of the file extension. But the icons in the explorer still look different. Is there a way to tell it to treat some other extensions like it treats .ixx?

Hi, @Robert N

The icon can be set by File type.

Such as C/C++ Code:

Currently, the module file type is shown as document, no module type is listed.
I'm afraid displaying module icon is not supported.
