Relative paths in per project favorites

[certainlyakey]

It would be nice to have a possibility to have relative paths in per project favorites. Thus we could copy a *-favs.json file from one project to another without a need for manually refavoriting all the files.

For example, many of my projects reuse composer.json, package.json, .gitignore located in the same folders with the same relative paths. With such a feature I could simply copy the favorites file from an old project to a new one or even commit the favorites file to a project boilerplate repo.
