Is there a way to copy the value of a custom field from one card onto another card on the same board

[Allison Owens]

I have a card with the custom field "Project Name" and a checklist of items that need to be created.  Once an item is created and checked on the checklist, that item becomes it's own card in a separate list.  

I would like for the "Project Name" value from the original card to carry over onto the new card that is created when the item is checked on the check list.

Is there a way to do this?

In general prefix like “trigger”, “new”, “copy” etc does not in the same was as , say eg {trigger cardname}, for custom fields you will have to 1) use wildcards in either cardname or description and have a second trigger to process the wildcard fields or 2) have a http request action using api to create a {httpresponse} for all custom fields.

Both approaches had worked for my clients before but it does involve advanced use of Trello automation.
