Hi, is there a reason why not all variables are available for dynamic data attachment? Specifically some metadata / server-generated variables?
I can see use cases such as:
- Use _uuid to check for duplicates without creating an error when editing the form
- Use start/end/_index to find the most recent submission (technically might be possible by creating a custom datetime variable but would be a cleaner solution)
- Only allow child forms for a given ID to be filled out if the parent form with the same ID has been validated
Is this something that would be possible / is planned at all?
