Create git PR from workspace

As a developer I would like to be able to create a pull request to my connected repository branch from the Fabric workspace.

Imagine you have a DEV workspace connected to your main branch. Your development process is to create feature branches/workspaces for feature development and only changes via pull requests can be merged into your main branch. This leads to the situation that no changes in the DEV workspace can be merged into main branch because only commits are possible.
