Automatically fill label field

I am using Endnote X8 (Mac-Version) and would like to automatically fill the field “label” when creating a new reference. The label should be a composition of the authors name and the last two digits of the publishing year. Is it possible to fill this field automatically?

At this time, there is no way to automate that process. When you create the new reference, that information will have to be manually entered into the Label field.
