You want to run a pipeline on a specific branch as part of your cron job, but you're unable to select in the trigger creation.
Create a pipeline with the cron trigger you want to use.
In this pipeline, add the following step:
codefresh-run: title: Run a codefresh pipeline type: codefresh-run arguments: PIPELINE_ID: <project-name/pip_name> TRIGGER_ID: <trigger_id> BRANCH: <branch-name>
Repeat for all branches you wish to run.
