New automations for sub-items

Any idea if more automations will be sub-item accessible?
We use sub-items as a list for multiple things per project (ie: Glass/Metal/Screws/Material), using it to mark different items ordered/not ordered/needs to be fabricated.
We are looking to set an automation similar to “every time period if status is then notify” (This currently does not work with sub-item status). We would use this to catch items that are not ordered/fabricated that don’t get caught visually.
