Re-initialize STRUCT variables

Hi,
I have a structure like this:

MY_STRUCT :STRUCT
  iInt    : INT := 42;    
  xBool   : BOOL := TRUE; 
  rReal   : REAL := 3.14; 
  sString : STRING[20] := 'Default'; 
END_STRUCT

In my code, I need to re-initialize a variable of this type. Currently, I declare two variables: myStruct_1, which changes during runtime, and myStruct_default, which remains constant.
To reset myStruct_1, I assign it like this:

myStruct_1 := myStruct_default;

The problem is that when the structure has hundreds of members or contains large arrays, memory usage becomes significant , since I’m duplicating the memory required.
Is there any other way to re-initialize a struct variable?
Something like:

myStruct_1 := MY_STRUCT();

Thanks, Marcello
