Sharing :: How To Grant Permissions For Domain User To Directory

I started getting into IT (as a job) a little less than a year ago, though I've been working with computers for close to 20. So networking was never something I was into while working on computers at home. I've been handed a significant position at work and I am learning a lot as I go. I want to know how to grant permissions for a domain user to a directory without adding the user to all of the sub-directories and directories. The only way I've figure thus far is to grant permissions to said folder, then inside remove the "inherit permissions..." but then I have to manually remove the permissions to every other sub-folder.I want to add a single path to a folder by adding single permissions to each folder until the directory in question is reached.
