I currently have a patch (generated using git diff) that I want to apply to a repo. But due to certain limitations, I am unable to pull the repo locally. But I have full access of the repo via the gitlab GUI. I can create branch, generate merge request, etc. Is it possible to apply the said diff via the GUI to create a branch, assuming there is no conflict.
(I know I can edit individual files and commit it but I have multiple files and I want to apply just the diff and not risk copy and paste errors.)
