Can you move a card within another card?

[Laura McLaren]

I am trying to move a card into another card, sort of as a "sub card" but I haven't been able to find a way to do that. Is it possible?

Trello do no have cards within cards, but you can link cards to each other (by going to a card, choose attachment and select/search/past link to other card)
