Suggestion: appended/prepended Data of nested 2.Loop will be reset.

If I make nested 2 HS-Loops or 3 HS-Loops,

the appended/prepended Result of 2.Loop will be reseted, if 1.Loop go again interation.

for example

1.Loop(1) - 2.Loop: save X1 (X1 = a result of 2.Loop of 1.Loop(1))

1.Loop(2) - 2.Loop: reset saved X1 and gather newly X2.

It would be cool, if every result of 2.Loop as Tree structure to be saved.
