Add an option to select specific folders inside a directory

Feature request for product/service

Cursor IDE

Describe the request

Add an option to select specific folders inside a directory without opening or indexing all subfolders.

For example, if folder X contains A, B, and C, I should be able to open only A and B while excluding C.

Currently, when using @ to reference files, files from all folders are listed, which makes navigation difficult in large projects
