title: Specify key file in a specific git repository
body: <p>I am using a collaborative user, so it is not possible to change global folder. I have a git repository connected with several remotes. I need to access different remotes with different rsa key. Is it possible to insert the key path within native git, e.g. maybe inside .git/config, so I don't need to repeat entering the key path when i am doing clones,fetches,pushes,pulls?</p>
  
  <p>Edit: I am aware of similar questions, for example <a href="https://stackoverflow.com/questions/14106982/specific-rsa-keys-per-git-repo">Specific RSA keys per git repo</a>, but it does not provide an exact answer to "per repo".</p>
