I'd say it's definitely not a bug.
It may be a "missing feature". There is an asymmetry, in that there are
- extract one row
- delete one row
- add multiple rows.
You could make a case for adding a feature to "add a single row". But I
wouldn't bother, because it's already so easy - see below.

The latest LC has the additional feauture of "automatic" sequences; i.e.
put [ sColSubtotalArray ] into tA
So, in fact you would simply do
