Simple re-writing of integral

Is there a built-in way of getting Maxima to recognize that

(%i92) integrate(diff(z(x+t), x), x, 0, 1);
(%o92)                limit   z(x + t) - limit   z(x + t)
                      x -> 1-            x -> 0+
(%i93) integrate(diff(z(x+t), x), t, 0, 1);
                              1
                             /
                             [   d
(%o93)                       I  (-- (z(x + t))) dt
                             ]   dx
                             /
                              0

should both return the same (viz., the former) result?

Thanks in advance,
