**Mood:** 😔
**Category:** Requests and ideas

Let us tie a session to an existing pr if we created the pr already. I have an existing branch and a pr. If I create from the branch I don't have a way to then associate with an existing pr later.

Issue 中没有指定文件、测试或入口点。首先跟踪桌面应用如何从现有 branch 创建 session，以及如何处理与 pull request 的关联，然后确定将该 session 链接到现有 PR 的流程。当从 branch 创建的 session 可以与其已创建的 PR 关联时，即视为完成。
