Access subitem ID via automation

Hi, it appears that you cannot directly access the subitem ID via automation.

When creating a new item in another board, the automation process currently allows you to link the parent item, but not the subitem and the subitem ID is not accessible in the automation process.

Is this something that will be improved in the near future?
Thanks.

I need this too. Right now, it requires extra API calls to get the correct subitem id in another board when I want to update it from a change in the item it created from this automation:
