how to change struct name in auto code generation

i have a struct define in my work space

ex:

data =struct                     
data.in1 = 1;                   
data.in2 = 2;                     
data.in3 = 3;

as expected it will create a struct called data. i was able to import it to my simulink file and run and used the data but when i generate the code and check the code. this is what it generate for the struct name and create data type called data under a weird name like this

 typedef struct {
              real32_T in1;
              real32_T in2;
              real32_T in3;
 }struct_ixqQNRfxxSL6hiWfBBiEsH;  <---- how do i change that weird name.

and it will create an instance of the struct called

 extern struct_ixqQNRfxxSL6hiWfBBiEsH data;

thanks
