Does Cursor Support AI Inquiries for the Entire Project?

I noticed that Cursor supports training embeddings for an entire project’s code locally. With that in mind, is it possible to directly ask the AI via CTRL+L which classes in the project could be converted to structs? The idea is for the AI to analyze all the code in the project and identify which classes in specific files could be changed to structs to improve memory efficiency.
If this feature is not yet supported, I hope it will be in the future!
