Is there a way in Card View to change a task to be a sub-task?

These tasks have a lot of data and have auto-numbering. I was hoping I could drop a card onto another to make it a sub-task or use a menu to make it a sub-task but not yet found anything.

There are so many cards involved that it would be time-consuming to rewrite each one as a sub-task.

Any suggestions?

Thank you,
