Monday.com and GUIDEcx

I'm building a recipe that creates projects from a Monday board's sub items as opposed to the item. I want to push the project ID back to the Monday board's sub items after project creation, but the Board ID field does not accept any datapills for the “Update Item by ID in Monday.com” action. The board ID for a subitem is unique so using the item’s board ID (which is static and easy to find) won’t work. Is it possible to update a Monday board subitem from Recipe Builder?
