Need option to not create worktree everytime

My project usually need to work with over 20+ repos at the same time. It is not realistic to create 20+ projects in GHCP desktop app. I currently use a utility local repo as the entrance. Only one GHCP project for this repo. I use instructions to allow the conversations in this repo to operate other 20+ repos. All conversations are created under this utility repo.

However, everytime when I create a repo by using the "+" button from the project level, it automatically create a worktree which is really unnecessary for my situation. I have to go to Home view to create new conversation to avoid adding new worktree.

Also when one of my conversation needs to create a child conversation, it also open a worktree automatically. It is very annoying that I have to manually clean up worktrees.

Every time when I fork from an existing conversation, it also creates a new worktree automatically.

I hope there are options for me to disable automatically worktree creation.

首先跟踪从项目级别的“+”按钮、Home 视图中的对话创建、子对话和 forks 进行 worktree 创建的流程。确定在这些入口中，禁用自动创建的选项应适用于哪些位置，然后验证禁用模式不会自动创建 worktree，同时仍可手动创建 worktree。
