Want to add a pointer in Box that points to Sharepoint or a shared drive files

Some files cannot be moved - they must remain where they are - on Sharepoint or on a shared drive.

I want to add something in Box so that I can click on the item and Box will navigate to the file (which is on Sharepoint or a shared drive) and display the file (or at least the folder/Sharepoint site)

Can I do that? If so, how?
