Create linked card from ONLY next unchecked item in checklist

[MD]

Hi all, I'm very new here and I've seen similar questions but not specifically what I'm trying to do, so I apologize in advance for a similar question.

I have a lot of main projects that will have checklists but the items are all dependent on the previous being complete. I'm looking for a way to create a checklist main task then automate creating a linked card to the next unchecked tasks only. 

I have a "Complete" list and I'd also like to be able to check off the item in the main checklist when it's associated card is moved to complete. Then at that point the first part should create a new card from the next item thats ready to go.

Anyone have any advice? Thank you

Hi MD, welcome to the Atlassian Community!

While this exact functionality isn’t currently available in Trello, I have gone ahead and created a new feature suggestion for you with our product team which you can access here: TRELLO-774

I would recommend you to visit that suggestion, log in with your Atlassian account, and click Start watching this issue on the right panel. This will help our product and engineering team understand more about which functionalities our users are interested in. Also, when the ticket is updated by our product team, you'll be notified via email.

I found a workaround that isn't ideal, but may help you. I created a rule that will create a new item and link the card, whenever an item with a specific name is checked. I used a wildcard to store the item value, along with other variables. Here's the result:

when the "{*} create card" item is checked, remove item "{checklistitemname}", add item "{wildcard1}" to checklist "{checklistname}", and convert the item to a linked card in list "List 2"

As for the rule to complete the items when the card is moved to the "Complete" list, you can create this one:

when a card is moved into list "Complete", find the first card linked in the attachments, and check item "{triggercardlink}"

 
Here's a video showing the result:
