✅ You can use the target_branches input for this, since v1.3.0.
Note that the target_branches input requires space-delimited branches, so finding these requires a checkout with a deep fetch and an extra step in your workflow.

It would be nice to be able to backport to all feature branches currently open named eg 'feature/*'. The configuration would be something like:
This would create a PR on each feature/* branch.
