Hi all, hope you are well. I would like to find out how I can delete duplicate cards within a card.

[Ocean Goliath]

For example : 

I work with stock that needs to be updated for different teams but I need to cancel out previous stock, some of the stock will remain the same for example tools, but then we have stock with quantities. The previous person handling this did not keep track accurately and I had to add the new stock lists but I need to figure out a way to make sure that the stock that is the same cancels out the duplicate. I'm not sure if that makes sense, thank you

Hi Ocean, welcome to the Atlassian Community!

I'm not sure if I understood your use case. Could you please share more details about how you use Trello? For example, when you mention "stocks that needs to be updated" are you referring to boards, cards, or lists?
If you want to know how to call each Trello component, I suggest checking our Trello guide:

I'd be happy to take a further look after having these details.
