Thank you, also for the follow up in reporting the bug.

I have playing around with \item at various positions but hadn’t considered using \itemtag.

As a more general question:

My understanding is that in a tabulate environment \NI is short for \NC \itemtag \NC

Yes but you can also write \NI[<reference>] which is short for \NC \itemtag[<reference>] \NC

Is that the case as well in a TABLE environment. E.g., \NI is short for \bTD \itemtag \eTD?

There is no shortcut for the \itemtag command for natural tables.
