How do I set the first column to a unique Item ID?

I’m looking to set the first column to a unique item ID, but there doesn’t seem to be that option. I can make any other column a unique item ID except the first–but the first is where it’s the most important, right? Can someone point me in the right direction?

hi @ike5

This can be done with this app Below is the recipe for it.

It overwrite the leftmost column with the generated ID when a new item is created.

More info about fields that can be used (year, quarter, month etc) can be found here
