When we update a branch with an active pull request, the pull request is updated. This is OK for smallish branches but often gets annoying. For larger ones, we use Code Collaborator. Bitbucket has an integration that auto-updates the collaborator review whenever the branch is updated... however, in our workflow a branch might be updated many times before the author is ready for the next round of review... if the integration auto-updates Collaborator every time the branch updates it would be completely unworkable.
Is there a way to set the normal pull requests, and the Collaborator integration such that I as the branch author can choose to trigger or not trigger the new review?
