How to ignore/exclude all files under a directory, or a certain file type from inspection?

This does NOT include excluding it by adding the files to the csproj.

Right clicking on the directory and clicking exclude adds those files to csproj, which is a problem since this is a shared repo and these files should be included. I just want Rider to stop parsing all javascript files, or all files under a certain directory. Every other jetbrain's IDE can do this. So is the feature just not implemented yet, or is there a way to do it that I've missed? Since all the help text I've found around this doesn't apply to Rider.
