Kanban based on subitem Status

Hello, we track the status of actions at subitem level and at item level we only have a summary of the status of the subitems. We therefore cannot use the Kanban feature as it only feeds on status columns at the item level. Can you please make it possible that Kanban boards can also be built from status columns in the subitem level. thank you very much!!

You can use Subitem Kanban for the issue.
It allows you to manage your subitems in a kanban view. Group them according to their status and update status by just drag and drop.
