GFiles from non git root?

Hi, I have been looking at configuring the `GFiles` command. The issues I am having is that the command assumes that it should run the `git ls-files` command from the root of the repository, instead from where `vim` was opened.
This turns out great when you have a single git repository, but e.g. when I work we have large repos with with projects within the same git repository.
In this usecase I'd like to have `git ls-files` in `GFiles` run from where I opened vim, not the root of the project.

Is there anyway to achieve this? Thanks for the assistance!
