Automate creating a mirrored subitem

Hi everyone
I am currently looking into a rather complex workflow that involves several moving parts, but I will try and describe what I need as best as I can. I am also not sure if Monday can even support what I want to do within its current capabilities.
I need a button triggered automation that creates an item in a different board and then in the sub items of the newly created item mirrors the information from the original board. It also needs to be able to add more subitems to that newly created item.
Is there any way this might be possible?
