Can I consolidate only some media into a project

I have a project which is using some very large video files I have stored on my Mac for various uses. When I create a project, I don't import those huge files as I don't want multiple copies of them, but things like small clips of stills, the odd sound FX, etc, would be useful to be stored within the project. Is it possible to consolidate the project so that everything, apart from the huge 30 minute pro res video files, are copied into it?
