Adding new checklist item to checklist template and shows up on all checklists

[Heather Zbinden]

I have one checklist that I use on a lot of different cards. But checklists grow and evolve as things change in the process. Is there a way to create a checklist template but if you need to add an item, you can add the new checklist item to the template and it will automatically add it to that checklist across boards and cards that have a "copy" of the checklist template?

@Heather Zbinden Here's a one off Trellinator piece of code that will do this kind of update:

You can update the checklist names etc. and run it in BenkoBot here:

Here's another example where a checklist item is added in a "main board" and the propagated out to a bunch of different project boards running inside Google Apps Script:

Theoretically, this is possible as long as you have enough commands on Bulter to do so. What I'd do is create a sort of "mastercard" for each one (or just all your boards) wherein there's a checklist that has the item links to each of the cards with your checklist on it. I.E. say you have three cards with your checklist (Lets call it "Template Checklist") and one mastercard. The master card has a checklist named "Card Links" and the three items in it are the three card links to your three cards with template cards. If you made a master card, you would have to add all the links by hand, but with a command like "When the "Template Checklist" checklist is added to a card, find a card with link "(the master card link)" and add item "{triggercardlink}" to checklist "Card Links" it would just update automatically.

Use another command like this: "When an item starting with "{*}" is added to checklist "Template Checklist", remove the item from the card, find a card with link "(the master card link)", for each card linked from an item in checklist "Card Links" add the "{checklistitemname}" item to checklist "Template Checklist"

Maybe there's an easier way to do this, but this was the first thing that came to mind. Sorry if this was confusing
