Is it possible to have a stateless form, via workflows or other means, create a parent record and add a row to its related subform? I know how to have a stateless form add a record to a form via workflows. I know how to add records to a subform via parent form w/information from the parent form. What I have not been able to figure out is how to have a stateless form add a record to a parent form and its subform all in one go. I believe at least one reason for this is that the parent record record ID has yet to be created and therefore the link between the two forms cannot be created. Does this mean it cannot be done?

My Forms:

New Item (Form)

    Item SKU

    Item Name

    Item Price

    Item Description

    

    Add Stock (SubForm)

        Qty Added

Add Stock (Form)

    Item SKU (Lookup linked to New Item Form - Item SKU)

    Item Name

    Date Entered

    Qty Added

Add Item (Sateless Form)

    Item SKU

    Item Name

    Item Price

    Item Description

    Qty Added

Volunteers, many of them older, will use mobile device to scan barcodes via Add Item stateless form and fill in remaining fields. Once submitted a new item is added to the database and a related Add Stock record is added.(at least that's what I would like to happen.) I know this can be done via the regular form/subform but there are extra steps related to adding Qty Added to the subform and I want to remove as many extra steps as possible to avoid confusion.

I'm not always best at how to phrase what I need so please let me know if i need to explain further.

Cheers,
