Can I link checklists on two different cards?

[Max_Dickinson]

I would like to be able to link checklists together, so that when an item, or multiple items (all the items in the checklist) are checked it automatically completes an item in the other checklist.

So for example...

Card A (PIZZA 1) has a checklist called 'Pizza Toppings'. The checklist reads:

1. Cheese

2. Meat

etc... 

Card B (Cheese) has a checklist called 'Cheese toppings':

1. Mozzarella

2. Cheddar

Card C (Meat) has a checklist called Meat toppings: 

1. Pepperoni 

If both items in checklist 'Cheese toppings' are complete, then the 1. Cheese item in Card A's 'Pizza toppings' checklist should be automatically completed. 

Hoping someone can help. Thanks!

Hi @Max_Dickinson 

You just need 3 butler rules : 

The first rule allows to check item in the task when the sub task is done

when a card is added to list "Done", for each card linked in the attachments, check item "{triggercardlink}"

The second rule allows to consider a task as done when all checklists are completed

when all checklists are completed in a card, move the card to the top of list "Done"

 The third rule allows to link task and sub tasks

when an item is added to checklist "{*}" by anyone, convert the item to a linked card
