Hi,
I am looking to create automation that will update the start and end dates of an initiative in a company-managed project when certain corresponding date fields are updated on the Idea issue in a separate Jira Discovery project.
Unfortunately, when creating the automation, the date field(s) I need from the Jira Discovery project don't show as options to populate the date field in the other project. (See screenshot)

(In my example, the date field that triggers the update is "Execution Start" from the team-managed Jira Discovery project; but I can't use that field's value to populate the "Start date" field over in the Jira Software project.)
I am guessing this is because the field in Jira Discovery is not a standard field, and is lost in the mess of team-managed fields.
Any advice?
