how to create a linked sub stask

[ME]

I have created a Parent card -> subtask (childcard)

is it possible to create a new subtask in the childcard that still links to the Parentcard?

Hi @QC QC ,

I am not sure of getting the point here but if you open the card and go to atachments you wil be able to atach a TRello a card. Then you will be asked to connect that card between them.

So then you have in parentcard a link to childcard and all the way around.

The parent card is created on a different board. and the childcard is send to another bord. 

and from this child card I would like to make new subtask which is still linked to the original parent card.
