Sync checklists - On one board all card checklists synced to a one master checklist

The end goal

My Trello board has many cards.

In that single board, some cards have checklists, with specific title "Shopping".

I want a card, for examle "MASTER CARD" to show one master "Shopping" checklist which includes "Shopping" list items from all other cards.

2 way sync - if I edit a list on a card, it will edit list on the "MASTER CARD"

 

Question

Is there any way to do it without using Trello API? I checked into Automation but I feel like I have not enough rules to achieve this. Specially 2 way.

Not specific to your scenario, I have worked on one without the use of API. It is one directional. For bi-directional you need to be careful not to go into a loop.   For 2 way, which is obviously more challenging, i used webhooks and that means some code at the endpoint. If you have more than 100 (or 150) links, Trello iteration through a checklist of cardlinks will not work. The other challenge is how to maintain the cross references when new cards are added. 

The other issue will be same checklist or item names. These are only identifiable by iD and the list not relationship across them. 

You are probably aware that there is Unito.
