Someone asked me how to connect a board with the last created item on another board, so I created the solution and am submitting it here. 
The Problem:
Connecting 2 boards to each other, but only getting the last created item.
The Use Case:
See the last donation from the Donation board as a mirror column in the Donor board.
The Caveat:
monday’s “overwriting” connect board automation logic only works on the board where the automation is created, and not where the connection is going.
In our use case, when a new donation is submitted in the Donation board, we want to overwrite the connect board column in Donor board to only show the last donation in the Donation board. This will not work with monday’s current automations.
The Solution:
There are 2 solutions you can use: App Automations or Workflow (only if you have enterprise).
App Automation
Download the app Advanced Item Link & Match.
Use their reverse logic to get the correct results.
Workflows
If you have an Enterprise account, you can create an easy workflow that’ll find the matching value, clear any previous connection, and then connect to the newly created item.
