For advanced automations, I use the Record ID (e.g., searching for records by record ID, creating links in calculations fields to open records from other apps, among others.)
The issue is that you can only get that value by creating a single-line text field and then using the following automation to get the record id.
If possible, could we have something like this in the Advanced fields?
That will do what the automation above does but with the option to copy the ID (just like the Unique ID field).
