Hi, can someone tell me if it’s possible to mirror data from an automated parent item to its sub-items? I have an automation that creates a pulse, then creates a fixed set of 4 sub-items. I just need the date field of the parent item to copy over to the sub-items but can’t seem to get this to work with mirroring as it wants me to specify the item to mirror. Problem is since it is auto-generated, I cannot specify an exact item. Hope this makes sense. Any help would be appreciated. Thanks!!
While you can Connect and Mirror info from a parent item to a Subitem within the same board, I’m not certain you can automate this process. Autocreation of Subitems is a new feature and not yet fully fleshed out.
I’m thinking this might be accomplishable by Integromat/Zapier/Monday API but I can’t say for
certain.
Hopefully we see more sub-item support for automations in the near future.
Yes, that’s what it sounds like. I will look into Integromat. Thank you again Andrew!

Does anyone have an update to this topic?
My use case is taking documents from a “Documents” board, and linking them to a “Project” board. Each project involves completing many documents; so I’d prefer for an item on the Project board to simply be the overall task, and then have all its documents as subitems.
It’s fairly tedious to go through and link 1 document for each 1 project subitem; however, it’s fairly quick to link 10 documents to 1 project item, so I’m wondering if there’s then a way to “convert” that link into subitems.
Hey Jack! Unfortunately there is no native way to automatically convert a linked column of items into subitems. Whilst you could connect and re-mirror the documents from the parent item into the subitem, if you want each of those documents to represent a subitem, you would need to manually make this change. I apologise for the setback here - this is certainly feedback we will share internally 
Am also in need of this – this would be particularly handy with the timeline column, for those who use gantt charts a lot.

I echo this request. However, I want to clarify how our company plans to use the feature. When a new Item is created, a subitem is created by automation. I would like to be able to take the Item Name and have it automatically copy/paste to the Subitem name. To take it even further, it would be really cool to have it add a version.
Example:
Main Item: Monday Project
Subitem: Monday Project v.1
Similarly, we have a “Project #” at the Main Item level. I would like this value to copy to the corresponding “Project #” field in the subitem. Currently, I can do a mirror column from the main item, but it is much faster to copy/past the value. Automating would cut back a lot of errors I see from my team, where they forget to enter the value.
