u;.n is meant to apply the monad u .   However, it can 
do what I think you asked, in so doing kicking and screaming 
all the while:

   cut1=: 1 : '(-:"_1 _ {.)@] (>@{...@[ u >@])/@|:;.1 (<@[ ,. <"_...@])'

   'aa' <@,~ cut1 ' now is the time'
+------+-----+------+-------+
| nowaa| isaa| theaa| timeaa|
+------+-----+------+-------+
   'bbb' <@,~ cut1 ' now is the time'
+-------+------+-------+--------+
| nowbbb| isbbb| thebbb| timebbb|
+-------+------+-------+--------+
