Not sure if this is a bug or if I'm missing some setting somewhere, but we've recently moved our repository from Github to a Bitbucket server solution (not bitbucket.org).
Now usually I would be able to create a PR directly inside Sourcetree by right-clicking the branch I want to start from and then choosing `Create Pull Request`.
I can still use this feature, but problem is that Sourcetree opens up my browser pointing towards our old Github repository (which hasn't been removed yet and probably never will).
How do I make the `Create Pull Request` point to our new repository URL?
