Research direction

Start by reproducing the issue with gh pr edit --base <your-parent-branch> and inspect the reported updatePullRequest GraphQL error. Determine whether stacked pull requests can support changing the base branch, then document the limitation or define the behavior needed for staging and multi-feature workflows.

Description

This feature could be better for code management if it can be used for projects with multiple environments since I cannot change the default base branch main to other branches (like staging, or to break a branch into many features and merge into it for better testing)

I have tried the following

# In your local repo
gh pr edit --base <your-parent-branch>

And I got

GraphQL: Cannot change the base branch because the pull request is part of a stack. (updatePullRequest)

I would love an update or explanation for this
