How to track Advanced Checklist Due Dates globally (Dashcards / Workspace Table)?

[ds]

Hi everyone,

I'm using Trello Premium to manage a training center/CRM. Each learner has a card, and their specific training milestones are tracked using Advanced Checklists (with specific due dates assigned to each checklist item).

My Goal: I want to create a centralized "Health Check" dashboard for my team. The idea is to have a global view (ideally using the Dashcards Power-Up) that counts all cards across multiple boards where at least one checklist item is overdue or due today.

The Roadblocks I've hit:

1. Dashcards / Filters: It seems Dashcards and Workspace filters only read the main Card Due Date, entirely ignoring Advanced Checklist item dates.

2. Butler (Due Date Automations): I tried to create a time-based automation to bypass this (e.g., "The moment an item in a checklist is due -> add a red label to the card"). However, Trello's time-based triggers only seem to work for Main Card Due Dates or Custom Fields, not checklist items.

My Question: Is there a clever workaround or a specific Power-Up to aggregate and track checklist due dates globally?

I know I could replace my checklist items with multiple "Date" Custom Fields to make it work with Dashcards, but Advanced Checklists are much more visually convenient for my trainers. Has anyone successfully built a dashboard tracking checklist item deadlines?

Thanks in advance for your help!
