When viewing an issue, its list of sub-tasks only displays Title, Issue Type, Status and Assignee.

I would like to also see the issue key (e.g. PROJ-123) as a column.

In self-hosted JIRA this can be set using the Advanced Settings "jira.table.cols.subtasks" property, but Advanced Settings are not accessible to us cloud users.

Can you change the global configuration to include this field? All other issues in all other screens are immediately identifiable by their key, so it seems like an oversight to not show this property on the list of sub-tasks.
