Stack operations in RPN mode on the Prime are very limited and a program cannot manipulate the stack. However we can use some tricks to achieve "almost" what you need.

The following program assigns to the user key Shift Right_arrow a function which returns to the command line the different elements of the list in the stack level 1 (if there’s one), then pressing Enter will push these elements to the stack.

Code:

KEY KS_Right()
BEGIN
 IF TYPE(Ans(1))==6 AND Entry==2 THEN
  RETURN ΣLIST(EXECON("STRING(&1)+\" \"",Ans(1)));
 ELSE
  RETURN −1;
 END;
END;

Note: I’ve done limited testing so there may be some cases where it doesn’t work correctly.
