We've migrated a lot of builds from Bamboo to Bitbucket Pipelines.
In order to keep our monorepo but have many parallel build pipelines for different parts of the repo we're using the atlassian/trigger-pipeline pipe extensively.
When viewing builds for a repository which is triggered by the pipe, it's really hard to find out which source build pipeline triggered the pipeline.
We could update each of our atlassian/trigger-pipeline usage to include a source repo/build variable but it would be a lot more consistent if this was a feature that came out of the box somehow
